Merge branch 'jc/name-rev-stdin'

"git name-rev --stdin" does not behave like usual "--stdin" at
all.  Start the process of renaming it to "--annotate-stdin".

* jc/name-rev-stdin:
  name-rev.c: use strbuf_getline instead of limited size buffer
  name-rev: deprecate --stdin in favor of --annotate-stdin
