Re: git-rev-list: make --dense the default (and introduce "--sparse")

This actually does three things:

 - make "--dense" the default for git-rev-list. Since dense is a no-op if 
   no filenames are given, this doesn't actually change any historical 
   behaviour, but it's logically the right default (if we want to prune on 
   filenames, do it fully. The sparse "merge-only" thing may be useful, 
   but it's not what you'd normally expect)

 - make "git-rev-parse" show the default revision control before it shows 
   any pathnames.

Btw, if it wasn't obvious, this has some subtle (and very nice) side 
effects.

For example, try this:

	git log git-fetch.sh

and notice how "git log" automagically became able to give per-file logs. 
With _zero_ changes to git-log.sh itself ;)

And same old rev-confusion-avoidance:

	git log -- gitk

to make clear that you want to get the log of "gitk the file", rather than 
"gitk the branch".

Magic.
