[PATCH v0 0/2] git-less: a specialized pager for git-log

[Hitoshi Mitake <h.mitake@gmail.com>]

Hi Junio C Hamano and git people,

I'd like to post this patch series for adding a pager program for git-log,
named "git-less". It seems that less is today's the most popular pager for
git-log. But I don't think that less is confortable pager when its input is come
from git-log. Because less treats its input as a simple text. So less cannot
recognize the end of each commit.

If the pager can recognize the end of each commit, more confortable viewing of
git-log's output will be possible.

So I'd like to introduce git-less, and the modification of git itself to support
this pager.

The main difference between less and git-less is recognition of each commit.
With this feature, git-log specific functionalities can be implemented. e.g.
* move with commit unit. Under git-less, hitting 'h' key means move to previous
  (parent) commit, 'l' means move to next (child) commit.
* commit local regex search. regular expression search limiting its range within
  commit, not entire log. I assigned '\' for commit local forward regex search
  and '?' for commit local regex search.

And other features like yanking commit ID might be implemented simply (not
implemented yet).

For implementing this feature, I had to make modification of git-log
* Changed output for inserting ETX (0x03) between each commit.
* Added new configuration parameter for git-log only pager: "log.pager".
  git-less only focuses on git-log, so it is not suitable for git-grep, etc.

This is the reason why I'm posting this patch. git-less is not git-independent
program. The source code of git-less have to be integrated with the git tree.
I understand this is not so good manner. And the source code is still dirty and
may be buggy, but I believe that this new pager is useful. I'd like to hear your
feedbacks.

Thanks,
