Modify commit-msg or post-commit git hooks to properly sync version with current commit

[jeffrey-cochran]

If using git from the command line, the commit-msg hook is invoked after the commit process is started; so, the flags in the message are parsed and the version file is modified after the commit completes (i.e., they're not staged in time).

Potential fix would be to include a check for staged version file in the post-commit hook and, if it's present, amend the commit to include it.

This is not an issue for folks using JGit with Eclipse.
