This is somewhat offtopic, but does anybody remember why $w (and
only $w) has to be checked against '*', instead of [ -n "$w" ]?
The primary reason I ask is because from time to time I hear people
who forget what these *#$% line noises mean and have been wondering
if we can add a GIT_PS1_SHOW_STATE_MNEMONIC option that shows these
with mnemonic letter sequences (e.g. "wsu" for dirty working tree,
unmodified index, with stash and untracked files).
