[PATCH v5 0/1] MR5402: wmic.exe: Support interactive mode and piped commands

[Louis Lenders (＠xe)]

See also https://bugs.winehq.org/show_bug.cgi?id=56361

This patch makes piped commands work like for example "echo os get version|wmic" or "type file.txt | wmic" where file.txt contains some commands.
(probably used by program in aforementioned bugreport)

Also support interactive mode (wine wmic.exe)

Marked for now as draft.
