One major issue with the pre-hook so far was partially staged files,
because it used filenames for php lint. These changes will make the hook read the file contents from the index instead.
Great thanks to David Soria Parra.
prepare-commit-hook now uses `git symbolic-ref HEAD` instead of reading
$GIT_DIR/HEAD directly. This seems to be a more portable solution.
Thanks to Chris (cs278/ToonArmy) for the suggestion.
This pre-commit hook utilises PHP's command-line -l (lint) option, which
checks for syntax errors. In case of an error the commit is rejected and
the error displayed.
Testing is welcome.
Git supports several hooks, some of which are client-side. The
prepare-commit-msg hook is run right after a `git commit` call, before
the editor is opened. This allows the initial message to be altered.
This hook will check if the current branch name begins with `bug/`, in
which case it will prepend `[$branchname]` to the commit message. This
makes it easier to create proper commit messages.
