[PATCH 1/2] Update the bash prompt from 'applied' instead of the obsolete 'current'

Signed-off-by: Robin Rosenberg <redacted>

s�ndag 20 maj 2007 skrev Yann Dirson:

Note that "tail -1" gives a warning with newer versions, "tail -n 1"
should be the proper call.

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

Also I'm not sure it is a good way to look at "applied" file, since
Karl IIRC has plans to change this.  Better call "stg top" and not
touch that again :)

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 :/
