[PATCH] rev-list: add --branches, --tags and --remotes

["Uwe Kleine-König" <Uwe.Kleine-Koenig@digi.com>]

These flags are already known to rev-parse and have the same meaning.

This patch allows to run gitk as follows:

	gitk --branches --not --remotes

to show only your local work.

Hello,

I'm not sure that I catched all locations where to add these three new
options.  Maybe I missed something in the docs?

Best regards
Uwe
