Re: [PATCH 6/8] ls-tree: work from subdirectory.

Without pathspec, ls-tree is a pretty-printing version of

behaviour of ls-tree for that purpose.

You're right, we need to keep the "-r" behaviour. 

Having said all of the above, I do understand why we would
_also_ want the behaviour parallel to ls-files, not /bin/ls
behaviour.  Maybe we should have both?  Either rename the
current ls-tree to browse-tree, and make the one that parallels
ls-files the new ls-tree?

If you take my last patch and make "ls_flags" default to 0 again, it 
should work correctly.

The way to traverse into directories (a la qgit/webgit) is to just give 
the SHA1 name of the directory. Ie

	git-ls-tree HEAD

gives us a single level, we see:

	...
	040000 tree b2d1264f85148d18c5ae9864d73d65737b0a1734    t
	...

and then we can just do

	git-ls-tree b2d1264f85148d18c5ae9864d73d65737b0a1734

to get that level. I assume that that is what qgit/webgit already does (I 
sure hope so, otherwise they're just wasting time, making the tools 
re-parse the trees over and over again for no gain).
