[PATCH/RFC 0/3] enable color prompt in non-pcmode

The use of colors in a prompt is only possible in pcmode (using the variable PROMPT_COMMAND).

Make color prompt work in non-pcmode (using the variable PS1) for both Bash and ZSH.

This requires editing __git_ps1() and __git_ps1_colorize_gitstring(), which have duplicate code to handle the prompt gitstring and color codes.

Prior to enable colors in non-pcmode, refactor __git_ps1() and __git_ps1_colorize_gitstring().
