Merge branch 'jk/pending-keep-tag-name'

History traversal with "git log --source" that starts with an
annotated tag failed to report the tag as "source", due to an
old regression in the command line parser back in v2.2 days.

* jk/pending-keep-tag-name:
  revision.c: propagate tag names from pending array
