refs: show --exclude failure with --branches/tags/remotes=glob
The documentation of `--exclude=` option from rev-list and rev-parse
explicitly states that exclude patterns *should not* start with 'refs/'
when used with `--branches`, `--tags` or `--remotes`.
However, following this advice results in refereces not being excluded
if the next `--branches`, `--tags`, `--remotes` use the optional
inclusive glob.
Demonstrate this failure.
