Prefixing your scripts is an awesome tips. A colleague told me he prefixed all his commands with ',' and I've started to do the same. '_' might clash with 'hidden'(?) shell expansions etc.

Sadly git doesn't allow for aliases with an comma-prefix, so all git aliases starts with a dot.

You can make symlinks or shell aliases that just reference git-add et al directly.
