Merge branch 'ag/rev-parse-all-exclude-fix'

"git rev-parse --exclude=* --branches --branches" (i.e. first saying "add only things that do not match '*' out of all branches" and then adding all branches, without any exclusion this time") worked as expected, but "--exclude=* --all --all" did not work the same way, which has been fixed. * ag/rev-parse-all-exclude-fix: rev-parse: clear --exclude list after 'git rev-parse --all'
