Merge branch 'jk/describe-omit-some-refs'
"git describe" and "git name-rev" have been taught to take more than one refname patterns to restrict the set of refs to base their naming output on, and also learned to take negative patterns to name refs not to be used for naming via their "--exclude" option. * jk/describe-omit-some-refs: describe: teach describe negative pattern matches describe: teach --match to accept multiple patterns name-rev: add support to exclude refs by pattern match name-rev: extend --refs to accept multiple patterns doc: add documentation for OPT_STRING_LIST
