Dunno.  I have only three concerns:

- It doesn't contaminate "my" namespace, where my installed programs,
  aliases, and shell functions are, i.e. it begins with an underscore.
- Its name conveys that it's git-specific.
- It's not called _git_complete, so the completion script (in
  particular at the end of _git()) won't misrecognize it as a
  completion function for the 'git complete' command, just in case
  somebody ever happens to have such a command or alias.

I'm not sure about the capital letters, but it fulfills all three.

It depends on what else will go into that bash-helpers.bash file.  If
I have to source it to use git completion or the git-specific bash
prompt, then I won't be very happy about it.

A reminder for what?

It's a configuration thing, so it will be used in .bashrc; I think
it's quite unlikely that it will be used interactively.
