Merge branch 'kn/ref-filter-branch-list' into maint

The rewrite of "git branch --list" using for-each-ref's internals that happened in v2.13 regressed its handling of color.branch.local; this has been fixed. * kn/ref-filter-branch-list: ref-filter.c: drop return from void function branch: set remote color in ref-filter branch immediately branch: use BRANCH_COLOR_LOCAL in ref-filter format branch: only perform HEAD check for local branches
