The PS1 functions in git-completion are simple functions which
work just as well for ZSH as for Bash. So, refactoring them out
allows ZSH users to also use them, 'standardizing' the prompt\
for Git.
The only thing not supported by ZSH is the
__git_ps1_show_upstream
function, so this functionality is simply forced disabled there.

This patch is mainly just moving the two functions
__gitdir
__git_ps1
out into a new file. However, the most "nasty" is the way this
file is then included from the original git-completion.bash
file, with
GIT_COMPLETION_BASH_ONLY=1
source $(dirname ${BASH_SOURCE[0]})/git-prompt-functions
where the variable ensures that only Bash will include the
__git_ps1_show_upstream
function call, and then the PS1 functions are loaded via a
dirname'd BASH_SOURCE[0]. I am by no means a Bash guru, so
others will have to evaluate the compatability of using this
technique outside of Bash on Linux. Relying on $0 at least,
does not work.
Someone will also have to verify the RPM part at the bottom.

+# This code was originially in git-completion.bash. However,
+# since this code works just fine also for ZSH, it was refactored
+# out, to allow ZSH users to source only the prompt functionality,
+# given that ZSH already comes with git completion of its own.
+#
+# Bash users might consider setting
+# PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+# while the ZSH equivalent would be
+# PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+#
+# You may set the following values to tweak the output of the
+# __git_ps1() function:
+#
+# GIT_PS1_SHOWDIRTYSTATE=true
+# Reports if in a dirty state
+# '*' means modified file(s)
+# '+' means added file(s)
+#
+# GIT_PS1_SHOWSTASHSTATE=true
+# Reports the current stash state
+#
+# GIT_PS1_SHOWUNTRACKEDFILES=true
+# Reports if there are untracked files in the repo
+#
+# GIT_PS1_SHOWUPSTREAM=auto
+# Places the divergence of repo against upstream, in variable 'p'
+# (Use $p in Bash prompts. Not available in ZSH prompts)
