[PATCH/RFC 07/12] docs: use <tree> instead of <tree-ish>

[Mark Lodato <lodatom@gmail.com>]

There is no longer any reference to <tree> in the documentation, since
all commands now accept a <tree-ish>, so remove the latter in favor
of the former.

Signed-off-by: Mark Lodato <lodatom@gmail.com>
---
I expect that this, along with the removal of <commit-ish>, is the most 
controversial part of the patch series.  I just don't see any reason to 
use the ugly and long <tree-ish> when <tree> is going unused!
