I'd been doing something a little crazy-sounding that I
thought I should share (for what it is worth). My problem
was that this expense Thomas mentioned was not just on first
entering a repo, but on *each* command, for some of my users
(long story... old hardware, wrong kind of "corporate
mandated" software, Windows... please don't ask <sigh>)
Also, instead of just a symbol, I wanted a *count* of how
many files are staged (git added), modified, untracked,
unmerged, etc. A color-coded number for each type would be
great.
But I couldn't run this extra stuff at every prompt. I
wanted it to kick in only when
* I change directories, or
* I switch branches, or the branch state (according to
__git_ps1) changes, or
* when I want it to, but I won't type a command (huh?)
The idea is that it should be as convenient and accessible
as the current __git_ps1, but it shouldn't really happen on
every prompt.
That last part is a bit of a hack, but basically, if you hit
enter twice in a row quickly at the bash prompt, you get the
more detailed stuff added to __git_ps1's output :-)
Sounds crazy but if you try it, you might just like it...

Comments welcome but please be kind. I'm still learning
git, compared to most of you lot :-)
