My man page doesn't mention -N being deprecated, but ok since -n 1 seems
to work here too.

Calling stg is too slow to be be used here. I that command in my first draft
for this function and people complained (see the thread named "Bash snippet
to show branch and patch in bash prompt"). It takes ~ 0.15s on here which is
very noticable, barely below my pain threshold.

We'll update the prompt when and if Karl breaks this.

It'd probably drain my battery too :/
