Subject: [PATCH] git-prompt.sh: update PROMPT_COMMAND documentation
The description of __git_ps1 function operating in two-arg mode was
not very clear. It said "set PROMPT_COMMAND=__git_ps1" which is not
the right usage for this mode, followed by "To customize the prompt,
do this", giving a false impression that those who do not want to
customize it can get away with no-arg form, which was incorrect.
Make it clear that this mode always takes two arguments, pre and
post, with an example.
The straight-forward one should be listed as the primary usage, and
the confusing one should be an alternate for advanced users. Swap
the order of these two.

Hi Junio
This removes most of the ambiguities :-)
Ack from me!
I still have some minor nits, but I'll leave that for another time when I'm less busy.
BTW, I haven't tried this yet, but if you pass 2 arguments to __git_ps1 when called from command-substition mode, I suppose it will think it's in PC mode and overwrite the PS1!
At some point, I'd like to see this code split off into "pc" and "cs" functions which call a common function to get the git status. But that's a major rewrite and it may involve more overhead, since each function should process the output of the common function in a different way.
Cheers
Simon
