Subject: [PATCH 2/2] Implemented 'g' command to goto a hunk.

When a minor change is made while the working directory
is in a bit of a mess (and the user should have done a
stash before making the minor edit, but didn't) it is
somewhat difficult to wade through all of the hunks using
git add --patch.  This allows one to jump to the hunk
that needs to be staged without having to respond 'n' to
each preceding hunk.
