	FR: Improve grep output (show function names, when possible)
Date: Sat, 25 May 2013 18:38:31 +0530

In terms of UI, git grep solution is inferior compared to
(which-function) proposal.  Both of these are in turn is much inferior
to current state of the art i.e., semantic-symref.

Semantic not only interfaces with grep, cscope backends but has the
necessary infrastructure to re-write the results in to a unified
interface.  More importantly it displays function context.

I am OK with this bug remaining closed.  

I have now moved the proposal for displaying function context to
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=14468.
