Re: Ensimag students projects, version 2013

A few small personal itches off the top of my head:

- Make git status -s show "state status" as well: this essentially
requires writing an equivalent of wt_status_print_state() for use in
wt_shortstatus_print().

- Make the -s and -b switches in git status configuration variables.
I currently have status aliased to status -sb, and this is less than
ideal.

- Make the -3 and -c switches in git am configuration variables.  I
have an alias.

- Create an advice.ui (like color.ui) to turn off all advice.  I don't
need advice.
