Ali Utku Selen 76abcc1d1e repo status to print project name on clean gits
repo status just prints "# on branch oprofile" if you have branched
in clean status. This doesn't really tell which branch is meant.

Instead we can use the same syntax with modified gits which will
give us detailed information.

helpDescription = """
'%prog' compares the working tree to the staging area (aka index),
and the most recent commit on this branch (HEAD), in each project
specified. A summary is displayed, one line per file where there
is a difference between these three states.
The -j/--jobs option can be used to run multiple status queries
in parallel.
Status Display
--------------
The status display is organized into three columns of information,
for example if the file 'subcmds/status.py' is modified in the
project 'repo' on branch 'devwork':
project repo/ branch devwork
-m subcmds/status.py
The first column explains how the staging area (index) differs from
the last commit (HEAD). Its values are always displayed in upper
case and have the following meanings:
-: no difference
A: added (not in HEAD, in index )
M: modified ( in HEAD, in index, different content )
D: deleted ( in HEAD, not in index )
R: renamed (not in HEAD, in index, path changed )
C: copied (not in HEAD, in index, copied from another)
T: mode changed ( in HEAD, in index, same content )
U: unmerged; conflict resolution required
The second column explains how the working directory differs from
the index. Its values are always displayed in lower case and have
the following meanings:
-: new / unknown (not in index, in work tree )
m: modified ( in index, in work tree, modified )
d: deleted ( in index, not in work tree )
