Junio C Hamano dcd6a8c09a Merge branch 'nd/diff-parseopt-4'
Fourth batch to teach the diff machinery to use the parse-options
API.

* nd/diff-parseopt-4:
  am: avoid diff_opt_parse()
  diff --no-index: use parse_options() instead of diff_opt_parse()
  range-diff: use parse_options() instead of diff_opt_parse()
  diff.c: allow --no-color-moved-ws
  diff-parseopt: convert --color-moved-ws
  diff-parseopt: convert --[no-]color-moved
  diff-parseopt: convert --inter-hunk-context
  diff-parseopt: convert --no-prefix
  diff-parseopt: convert --line-prefix
  diff-parseopt: convert --[src|dst]-prefix
  diff-parseopt: convert --[no-]abbrev
  diff-parseopt: convert --diff-filter
  diff-parseopt: convert --find-object
  diff-parseopt: convert -O
  diff-parseopt: convert --pickaxe-all|--pickaxe-regex
  diff-parseopt: convert -S|-G
  diff-parseopt: convert -l
  diff-parseopt: convert -z
  diff-parseopt: convert --ita-[in]visible-in-index
  diff-parseopt: convert --ws-error-highlight
