[PATCH 00/10] fix bug, use existing enums

I have some feature changes planned for parse-options.[ch], including ones that allow us to delete some boilerplate (and sometimes buggy) code in built-ins by having the API do heavier lifting.

In adding anything to the API I've found it hard to deal with it using its own enums inconsistently, sometimes it's an "int", sometimes it's the "enum", and having the "default" cases makes it hard to assert that you've added things to all the right places.

2-6,7-10/10 is that rather straightforward conversion. 1,7/10 also have fixes to existing bugs that happened due to mixing up the enum fields in one way or the other.

Ævar Arnfjörð Bjarmason (10):
  parse-options.h: move PARSE_OPT_SHELL_EVAL between enums
  parse-options.[ch]: consistently use "enum parse_opt_flags"
  parse-options.[ch]: consistently use "enum parse_opt_result"
  parse-options.c: use exhaustive "case" arms for "enum parse_opt_type"
  parse-options.h: make the "flags" in "struct option" an enum
  parse-options.c: move optname() earlier in the file
  commit-graph: stop using optname()
  parse-options.[ch]: make opt{bug,name}() "static"
  parse-options tests: test optname() output
  parse-options: change OPT_{SHORT,UNSET} to an enum
