[PATCH 0/2] parse-options.c: remove OPT_ARGUMENT

We've only ever used parse-option.c's OPT_ARGUMENT() in one place, as it turns out we can use an OPT_BOOL there instead. and get a net reduction in code & complexity.

Ævar Arnfjörð Bjarmason (2):
  difftool: use "struct strvec" API in run_{dir,file}_diff()
  parse-options API: remove OPTION_ARGUMENT feature
