Re: Any objectsions to enhancing git-log to show tags/branch heads?

I'll fire up gitk, quickly look at the tags/branches, and then kill it

it dies.

So I'm wondering why we haven't arranged to have git-log show this
information, and whether there would be any objections if "git-log"
showed something like this:

Would there be objections in adding this to --pretty=medium (i.e., the
default), or would it be better to add something like tihs to
--pretty=full or --pretty=fuller?

The only reason why I could imagine not doing this by default would be a
potential performance problem if there were thousands of heads or branch
heads.

I'll do this gitk jump very often, too. Just to get the big picture where my
branches are (inside the commit graph). As they stay normaly on the tip, I
exit gitk long before it reached the root commit. What I'd like to have is
something which shows me _visually_ the the branches, e.g.

master
| next			commit comment for next
o  |		commit comment for master~1
|  o			commit comment for next~1
o  |	[ ... guess whats next :-)		you get the idea ...]
|  o
|  |
o /

tig comes near it, but it only linerarises the branches, so you can't see
where there was a mergepoint/fork. I'd really like these visuallization of
the commit graph in some of the text viewers. I normally don't care about
the _full_ commit text, only if I visually understand what's happening I'm
looking at the individual commits and the patches.

There was some tool (can't remember its name or who it wrote; but posted
here on this list) which visualizes  the relation horizontaly and not
vertically as shown above but has a limit of only displaying around 25 (not
sure about this number; but definitly below 30 commits) which was at least
displaying the commit graph which is _really_ really what I need.
