[RFC PATCH 2/3] Documentation/git-rev-list: s/<commit>/<object>/

[Matthew DeVore <matvore@google.com>]

git-rev-list has a mode where it works on the granularity of trees and
blobs, rather than commits only. When discussing this mode in
documenation, it can get awkward to refer to the list of arguments that
may include blobs and trees as <commit>. It is especially awkward in a
follow-up patch, so prepare for that patch by renaming the argument.

In addition to simply renaming the argument, also reword documentation
in some places such that we include non-commit objects in our
terminology. In other words, s/commit/object/ in any prose where the
context obviously applies to trees and blobs in a non-pathological way.
