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:+/$REL}]$ "
