rev-parse: introduce --exclude=<glob> to tame wildcardsjc/ref-excludes
Teach "rev-parse" the same "I'm going to glob, but omit the ones that match these patterns" feature as "rev-list". Signed-off-by: Junio C Hamano <gitster@pobox.com>

+--exclude=<glob-pattern>::
+ Do not include refs matching '<glob-pattern>' that the next `--all`,
+ `--branches`, `--tags`, `--remotes`, or `--glob` would otherwise
+ consider. Repetitions of this option accumulate exclusion patterns
+ up to the next `--all`, `--branches`, `--tags`, `--remotes`, or
+ `--glob` option (other options or arguments do not clear
+ accumlated patterns).
++
+The patterns given should not begin with `refs/heads`, `refs/tags`, or
+`refs/remotes` when applied to `--branches`, `--tags`, or `--remotes`,
+respectively, and they must begin with `refs/` when applied to `--glob`
+or `--all`. If a trailing '/{asterisk}' is intended, it must be given
+explicitly.
