Given a request for command-line usage information rather than some
more substantial action, the only friendly thing to do is to report
the usage information as soon as possible and exit.
Without this change, as "git gc" glances over the repository, it can
be distracted by the desire to report a malformed configuration file.

The git_config() function signals error by returning -1 in
two instances:
1. An actual error occurs in opening a config file (parse
errors cause an immediate die).
2. Of the three possible config files, none was found.
However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.
This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.

git-gui currently uses its own logic to determine the work-tree setting
but 'git rev-parse --toplevel' directly returns git's work-tree value
by calling get_git_work_tree() and is therefore always correct.
This fixes an inability to handle some repository configurations. In
particular where .git is a file containing a path to the real directory
(a cross-platform symbolic link).
To continue to support older versions than 1.7.0, setting the work-tree
by normalizing the --show-cdup value is more reliable as git-dir might be
outside the work-tree entirely.

respond in kind so the effort was lost when the filesystem boundary is
exactly at that directory.
Let git-repack pass a path under .git/objects/pack/ as the base for
its temporary packs.
This means we might need the $PACKDIR sooner (before the pack-objects
invocation), so move the mkdir up just to be safe.
Also note that the only use of *.pack is in the find invocation way
before the pack-objects call, so the temporary packs will not suddenly

And as a side-effect of 2794ad5 (fast-import: Allow filemodify to set

the tree entry for root:foo/bar to refer to the specified tree.

For terminal tests that capture output/stderr, the TTY prerequisite
warning does not quite work for commands like
test_terminal foo >out 2>err
because the warning gets "swallowed" up by the redirection that's
supposed only to be done by the subcommand.
Even worse, the outcome depends on whether stdout was already a
terminal (in which case test_terminal is a noop) or not (in which case
test_terminal introduces a pseudo-tty in the middle of the pipeline).
$ test_terminal.perl sh -c 'test -t 1 && echo >&2 YES' >out
YES
$ sh -c 'test -t 1 && echo >&2 YES' >out
$
So:
- use the test_terminal script even when running with "-v".
- skip tests that require a terminal when the test_terminal
script is unusable because IO::Pty is not installed.
- write the "need to declare TTY prerequisite" message to fd 4,
where it will be printed when running tests with -v, rather
than being swallowed up by an unrelated redireciton.

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant. The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).
Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.
So leave off the "strange error" messages.
The result should look something like this:
$ git push sf master
Counting objects: 21542, done.
Compressing objects: 100% (4179/4179), done.
fatal: Unable to create temporary file: Permission denied
error: pack-objects died of signal 13
error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'

Or in the "controlled exit" case (contrived example):
