Silence a warning given when running git difftool --dir-diff and
there are no changes.
This is because command_oneline returns undef when the command has no
output, not ''.

The previous series introduced warnings to multiple places, but it
could become tiring to see the warning on the same path over and
over again during a single run of Git. Making just one function
responsible for issuing this warning, we could later choose to keep
track of which paths we issued a warning (it would involve a hash
table of paths after running them through real_path() or something)
in order to reduce noise.
Right now we do not know if the noise reduction is necessary, but it
still would be a good code reduction/sharing anyway.

Just like config and gitignore files, we silently ignore
missing or inaccessible attribute files. An existent but
inaccessible file is probably a configuration error, so
let's warn the user.

When we try to access gitignore files, we check for their
existence with a call to "access". We silently ignore
missing files. However, if a file is not readable, this may
be a configuration error; let's warn the user.
For $GIT_DIR/info/excludes or core.excludesfile, we can just
use access_or_warn. However, for per-directory files we
actually try to open them, so we must add a custom warning.

Before reading a config file, we check "!access(path, R_OK)"
to make sure that the file exists and is readable. If it's
not, then we silently ignore it.
For the case of ENOENT, this is fine, as the presence of the
file is optional. For other cases, though, it may indicate a
configuration error (e.g., not having permissions to read
the file). Let's print a warning in these cases to let the
user know.

The linked list describing sort options was not correctly set up in
opt_parse_sort. In the result, contrary to the documentation, only the
last of multiple --sort options to git-for-each-ref was taken into
account. This commit fixes it.

Documentation of git-for-each-ref says that --sort=<key> option can be
used multiple times, in which case the last key becomes the primary key.
However this functionality was never checked in test suite and is
currently broken. This commit adds appropriate test in preparation for fix.

The gettext .po files have a header, but it looks like the
translation specification for an empty string. This results in
_("") actually returning that header.
Check the input to _() and do not call gettext() on an empty string;
in some places, we run _(opts->help) where opts->help may be empty.

The bug report in http://stackoverflow.com/questions/11893688
observes that files are mapped into the wrong locations in
git when both --use-client-spec and --branch-detection are enabled.
Fix this by changing the relative path prefix to match discovered
branches when using a client spec.
The problem was likely introduced with ecb7cf9 (git-p4: rewrite view
handling, 2012-01-02).
