[PATCHv2 0/8] docs: use metavariables consistently

[Mark Lodato <lodatom@gmail.com>]

Update the documentation and usage statements to use metavariables, such as
<commit>, more consistently.  The biggest change is to drop the <tree-ish> and
<commit-ish> (or <committish>) notation and just use <tree> or <commit>, since
every command but commit-tree accepts tree-ishes and commit-ishes.  The "-ish"
terms are still kept around in various places where it makes sense to
differentiate between an actual tree or commit and a tree-ish or commit-ish.

This is a rework of my earlier patch set from March [1], with the following
differences:

- Drop the patch to commit-tree that makes it accept a tree-ish.
- Drop the patch dealing with <tag> and <tagname>.
- Leave -ish terms in comments and in places where they make sense.
- Rebase onto master (1b97434).  Some of the patches from before have since
  been accepted from other authors.
- Fix a problem that Junio noticed with the "grep docs" patch.
