Just a note:

this doesn't work with bash 3.2. I think they altered the way of
trimming variables in this version.

on systems with bash 3.2 installed, i get
[master!linus-2.6/vm/vm]$ 
with the example above.

on systems with bash 3.1, it works properly.

Sorry bout that, I knew it was a bit fragile.  Was rather
comical reading Junio's recent message about all the things not
to do if you want portable shell code and noticing my 6 line script
did 90% of them ;o)  Strange though, I downloaded Bash 3.2
and gave it a try and didn't see the problem here..

Wanna try this small change, to see if it helps? :

#!/bin/bash
BR=$(git symbolic-ref HEAD 2>/dev/null) || { echo "$@" ; exit ; }
BR=${BR#refs/heads/}
REL=$(git rev-parse --show-prefix)
REL="${REL%\/}"
LOC="${PWD%/$REL}"
echo "[$BR!${LOC/*\/}${REL:+/$REL}]$ "
