Merge branch 'jc/ref-excludes'

People often wished a way to tell "git log --branches" (and "git log --remotes --not --branches") to exclude some local branches from the expansion of "--branches" (similarly for "--tags", "--all" and "--glob=<pattern>"). Now they have one. * jc/ref-excludes: rev-parse: introduce --exclude=<glob> to tame wildcards rev-list --exclude: export add/clear-ref-exclusion and ref-excluded API rev-list --exclude: tests document --exclude option revision: introduce --exclude=<glob> to tame wildcards
