[PATCH 0/5 v3] log and diff: accept detached forms (--option value)

Since last version :

* I had missed several optional arguments, for which detached form
  should not be allowed (otherwise, --option --other-option is
  ambiguous). In most cases, my changes were harmless since the code
  had already checked for the parameterless form before reaching mine,
  but that was definitely bad anyway.

* One missing "return optarg;" (that even Jonathan had missed ;-) )

* One more test for "git log -S" failure (no argument to -S)

* Refactoring by Jonathan Nieder for --stat-*

* Rewording of commit messages.

Jonathan Nieder (1):
  diff: split off a function for --stat-* option parsing

Matthieu Moy (4):
  diff: parse detached options like -S foo
  diff: parse detached options --stat-width n, --stat-name-width n
  log: parse detached options like git log --grep foo
  log: parse detached option for --glob
