One thing I will not do after such a discussion, unless I am really really
interested in having the new feature personally myself, is to go back to
the discussion thread and assemble the pieces together to make the final
series of patches for inclusion. The responsibility for doing that lies
on the original contributor.
That is a perfectly reasonable policy, and I did not intend
to suggest that you should do that work. My apologies if
it seemed that way. Here is the first of 2 patches to
implement the 'g' command. I believe it is complete, but
I am not much for user interface. It works for me, but it
could be improved upon. (For example, I took your suggestion
and disallowed 'g' when there is only one hunk, but the
behavior feels clunky, although it is similar to an invalid
k/j entry.)

Subject: [PATCH 1/2] Add subroutine to display one-line summary of hunks.
This commit implements a rather simple-minded mechanism
to display a one-line summary of the hunks in an array ref.
The display consists of the line numbers and the first
changed line, truncated to 80 characters. 20 lines are
displayed at a time, and the index of the first undisplayed
line is returned, allowing the caller to display more if
desired. (The 20 and 80 should be made configurable.)
