Remove feature_grep in gitweb?

Howdy,

A feature_grep subroutine is defined in gitweb.perl, but unlike the
other feature_* subroutines there, it doesn't appear to be used
anywhere.  Should it be removed?

The 'grep' feature was marked in the comments as having project
specific config, but it lacked 'sub' key required for it to work.

No, it was oversight; it should be used in setting up 'grep' %feature
configuration, see below.

Thanks for catching this.
