Do not include refs matching 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 accumulated 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 /* is intended, it must be given explicitly.
