[PATCH v2 0/1] MR9007: wmic: Add a basic help option "/?".

[Louis Lenders (＠xe)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=45343

The installers from that bugreport use this (in Win7 mode) to check if wmic is present.
(The installer still fails after this patch as findstr.exe lacks
some support: "match_regexp character ranges (i.e. [abc], [^a-z]) are not supported")
