t9814: guarantee only one source exists in git-p4 copy tests
By using a tree with multiple identical files and allowing copy detection to
choose any one of them, the check in the test is unnecessarily complex. We can
simplify by:
* Modify source file (file2) before copying the file.
* Check that only file2 is the source in the output of "p4 filelog".
* Remove all "case" statements and replace them with simple tests to check
that source is "file2".

When the input is UTF-8 and Perl is operating on bytes instead of
characters, a diff that changes one multibyte character to another
that shares an initial byte sequence will result in a broken diff
display as the common byte sequence prefix will be separated from
the rest of the bytes in the multibyte character.
For example, if a single line contains only the unicode character
U+C9C4 (encoded as UTF-8 0xEC, 0xA7, 0x84) and that line is then
changed to the unicode character U+C9C0 (encoded as UTF-8 0xEC,
0xA7, 0x80), when operating on bytes diff-highlight will show only
the single byte change from 0x84 to 0x80 thus creating invalid UTF-8
and a broken diff display.
Fix this by putting Perl into character mode when splitting the line
and then back into byte mode after the split is finished.
The utf8::xxx functions require Perl 5.8 so we require that as well.
Also, since we are mucking with code in the split_line function, we
change a '*' quantifier to a '+' quantifier when matching the $COLOR
expression which has the side effect of speeding everything up while
eliminating useless '' elements in the returned array.

The test now fails because git-p4 does not properly detect

has been locked and reporting it to the user, so this is

merge: pass verbosity flag down to merge-recursive
This makes "git merge --quiet" really quiet when we call
into merge-recursive.
Note that we can't just pass our flag down as-is; the two
parts of the code use different scales. We center at "0" as
normal for git-merge (with "--quiet" giving a negative
value), but merge-recursive uses "2" as its center. This
patch passes a negative value to merge-recursive rather than
"1", though, as otherwise the user would have to use "-qqq"
to squelch all messages (but the downside is that the user
cannot distinguish between levels 0-2 if without resorting
to the GIT_MERGE_VERBOSITY variable).
We may want to review and renormalize the message severities
in merge-recursive, but that does not have to happen now.
This is at least in improvement in the sense that we are
respecting "--quiet" at all.

init: don't set core.worktree when initializing /.git
If you create a git repository in the root directory with
"git init /", we erroneously write a core.worktree entry.
This isn't _wrong_, in the sense that it's OK to set
core.worktree when we don't need to. But it is unnecessarily
surprising if you later move the .git directory to another
path (which usually moves the relative working tree, but is
foiled if there is an explicit worktree set).
The problem is that we check whether core.worktree is
necessary by seeing if we can make the git_dir by
concatenating "/.git" onto the working tree. That would lead
to "//.git" in this instance, but we actually have "/.git"
(without the doubled slash).
We can fix this by special-casing the root directory. I also
split the logic out into its own function to make the
conditional a bit more readable (and used skip_prefix, which
I think makes it a little more obvious what is going on).
No tests, as we would need to be able to write to "/" to do
so. I did manually confirm that:
push --signed: tighten what the receiving end can ask to sign
Instead of blindly trusting the receiving side to give us a sensible
nonce to sign, limit the length (max 256 bytes) and the alphabet
(alnum and a few selected punctuations, enough to encode in base64)
that can be used in nonce.
send-pack: unify error messages for unsupported capabilities
If --signed is not supported, the error message names the remote
"receiving end". If --atomic is not supported, the error message
names the remote "server". Unify the naming to "receiving end"
as we're in the context of "push".

show-branch: show all local heads when only giving one rev along --topics
"git show-branch --topics <rev> <revs>..." displays ancestry graph, only
considering commits that are in all given revs, except the first one.
"git show-branch" displays ancestry graph for all local branches.
Unfortunately, "git show-branch --topics <rev>" only prints out the rev
info for the given rev, and nothing else, e.g.:
$ git show-branch --topics origin/master
[origin/master] Sync with 2.3.3
While there is an option to add all remote-tracking branches (-r), and
another to add all local+remote branches (-a), there is no option to add
only local branches. Adding such an option could be considered, but a
user would likely already expect that the above command line considers
the lack of rev other than for --topics as meaning all local branches,
like when there is no argument at all.
Moreover, when using -r and -a along with --topics, the first local or
remote-tracking branch, depending on alphabetic order is used instead of
the one given after --topics (any rev given on the command line is
actually simply ignored when either -r or -a is given). And if no rev is
given at all, the fact that the first alphetical branch is the base of
topics is probably not expected by users (Maybe --topics should always
require one rev on the command line?)
This change makes
"show-branch --topics $rev"
act as
"show-branch --topics $rev $(git for-each-ref refs/heads
--format='%(refname:short)')"

sha1_file: squelch "packfile cannot be accessed" warnings
When we find an object in a packfile index, we make sure we
can still open the packfile itself (or that it is already
open), as it might have been deleted by a simultaneous
repack. If we can't access the packfile, we print a warning
for the user and tell the caller that we don't have the
object (we can then look in other packfiles, or find a loose
version, before giving up).
The warning we print to the user isn't really accomplishing
anything, and it is potentially confusing to users. In the
normal case, it is complete noise; we find the object
elsewhere, and the user does not have to care that we racily
saw a packfile index that became stale. It didn't affect the
operation at all.
A possibly more interesting case is when we later can't find
the object, and report failure to the user. In this case the
warning could be considered a clue toward that ultimate
failure. But it's not really a useful clue in practice. We
wouldn't even print it consistently (since we are racing
with another process, we might not even see the .idx file,
or we might win the race and open the packfile, completing
the operation).
This patch drops the warning entirely (not only from the
fill_pack_entry site, but also from an identical use in
pack-objects). If we did find the warning interesting in the
error case, we could stuff it away and reveal it to the user
when we later die() due to the broken object. But that
complexity just isn't worth it.

docs: clarify what git-rebase's "-p" / "--preserve-merges" does
Ignoring a merge can be read as ignoring the changes a merge commit
introduces altogether, as if the entire side branch the merge commit
merged was removed from the history. But that is not what happens
if "-p" is not specified. What happens is that the individual
commits a merge commit introduces are replayed in order, and only
any possible merge conflict resolutions or manual amendments to the
merge commit are ignored.
Get this straight in the docs.
Also, do not say that merge commits are *tried* to be recreated. As that is
