completion: fix completing unstuck email alias arguments
Completing unstuck form of email aliases doesn't quite work:
$ git send-email --to <TAB>
alice bob cecil
$ git send-email --to a<TAB>
alice bob cecil
While listing email aliases works as expected, the second case should
just complete to 'alice', but it keeps offering all email aliases
instead.
The cause for this behavior is that in this case we mistakenly tell
__gitcomp() explicitly that the current word to be completed is empty,
while in reality it is not. As a result __gitcomp() doesn't filter
out non-matching aliases, so all aliases end up being offered over and
over again.
Fix this by not passing the current word to be completed to
__gitcomp() and letting it go the default route and grab it from the
'$cur' variable. Don't pass empty prefix either, because it's assumed
to be empty when unspecified, so it's not necessary.

verify_pack: do not ignore return value of verification function
In verify_pack, a caller-supplied verification function is called.
The function returns an int. If that return value is non-zero,
verify_pack should fail.
The only caller of verify_pack is in builtin/fsck.c, whose verify_fn
returns a meaningful error code (which was then ignored). Now, fsck
might return a different error code (with more detail). This would
happen in the unlikely event that a commit or tree that is a valid git
object but not a valid instance of its type gets into a pack.

Make error message after failing commit_lock_file() less confusing
The error message after a failing commit_lock_file() call sometimes
looks like this, causing confusion:
$ git remote add remote git@server.com/repo.git
error: could not commit config file .git/config
# Huh?!
# I didn't want to commit anything, especially not my config file!
While in the narrow context of the lockfile module using the verb
'commit' in the error message makes perfect sense, in the broader
context of git the word 'commit' already has a very specific meaning,
hence the confusion.
Reword these error messages to say "could not write" instead of "could
not commit".
While at it, include strerror in the error messages after writing the
config file or the credential store fails to provide some information
about the cause of the failure, and update the style of the error
message after writing the reflog fails to match surrounding error
messages (i.e. no '' around the pathname and no () around the error
description).

If a branch name is longer than four characters then memcmp() reads over
the end of the static string "HEAD". This causes the following test
failures with AddressSanitizer:
And if a branch is named "H", "HE", or "HEA" then the current if clause
erroneously considers it as matching "HEAD" because it only compares
up to the end of the branch name.
Fix that by doing the comparison using strcmp() and only after the
branch name is extracted. This way neither too less nor too many
characters are checked. While at it call strchrnul() to find the end
of the branch name instead of open-coding it.

add "ok=sigpipe" to test_must_fail and use it to fix flaky tests
t5516 "75 - deny fetch unreachable SHA1, allowtipsha1inwant=true" is
flaky in the following case:
1. remote upload-pack finds out "not our ref"
2. remote sends a response and closes the pipe
3. fetch-pack still tries to write commands to the remote upload-pack
4. write call in wrapper.c dies with SIGPIPE
The test is flaky because the sending fetch-pack may or may
not have finished writing its output by step (3). If it did,
then we see a closed pipe on the next read() call. If it
didn't, then we get the SIGPIPE from step (4) above. Both
are fine, but the latter fools test_must_fail.
t5504 "9 - push with transfer.fsckobjects" is flaky, too, and returns
SIGPIPE once in a while. I had to remove the final "To dst..." output
check because there is no output if the process dies with SIGPIPE.
Accept such a death-with-sigpipe also as OK when we are expecting a
failure.

Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.
After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.
Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.
