[PATCH v3 00/10] update-index: migrate to parse-options API

[Jonathan Nieder <jrnieder@gmail.com>]

This adapts "git update-index" to use the parse-options API
(with resulting perks like nice "-h" output).  Doing so reveals
some potential improvements to parse-options infrastructure, too.

See [1] for the previous version.  This version incorporates the
last few suggestions by Stephen.  The iffiest bit is still
handling of the --cacheinfo option.

Thanks to Stephen and Junio for advice.  Patches applies to maint,
for no particular reason.

Jonathan Nieder (7):
  parse-options: clearer reporting of API misuse
  parse-options: move NODASH sanity checks to parse_options_check
  parse-options: sanity check PARSE_OPT_NOARG flag
  parse-options: never suppress arghelp if LITERAL_ARGHELP is set
  parse-options: allow git commands to invent new option types
  parse-options: make resuming easier after
    PARSE_OPT_STOP_AT_NON_OPTION
  update-index: migrate to parse-options API

Nguyễn Thái Ngọc Duy (1):
  setup: save prefix (original cwd relative to toplevel) in
    startup_info

Stephen Boyd (2):
  parse-options: Don't call parse_options_check() so much
  parse-options: do not infer PARSE_OPT_NOARG from option type
