I agree that it's ugly. How about the following:

I modified __git_ps1 to work both in PROMPT_COMMAND mode and in that 
mode support color hints.

This way there's one function, so no overlap.

Shall I send patches for the two changes separately (to support 
PROMPT_COMMAND mode and another to support color hints) or in one?

And what about zsh support? I doubt the PROMPT_COMMAND thing is 
compatible with zsh, but the command substitution mode should probably 
work, unless it is already broken by the use of % to indicate untracked 
files (when GIT_PS1_SHOWUNTRACKEDFILES is set). Unless it is tested 
further in zsh, I'd say it might be better not to claim zsh is supported.
