[PATCH 0/2] A bit of ref-filter atom parsing cleanups

The diffstat of the second patch doesn't show any benefits, but only because the first patch removed a callsite that would have benefited from it.

It merges cleanly with Karthik's "port branch.c to use ref-filter's printing options" series.

SZEDER Gábor (2):
  ref-filter, tag: eliminate duplicated sorting option parsing
  ref-filter: add function to parse atoms from a nul-terminated string
