[PATCH 0/6] MR6615: Cmd engine rewrite (part XXVII)

[eric pouech (＠epo)]

This is part XXVII of cmd engine rewrite.

It covers:
- fixing a regression introduced when looping up
  for program names with several dots in their names
  (eg. foo.bat can invoke foo.bat.cmd)
- fix an incorrect handling of 'SET =' command
- a couple of cleanups in SET command
