[PATCH 1/3] cmd.exe: Fix running programs from root of drive

[Jason Edmeades]

Supports c:\a.bat and c:\windows\a.bat by leaving the path with the
trailing '\'. When it was removed, the search path for c:\a.bat was
effectively the work directory on 'C:' and it fails to locate the program

Should fix bug 11724
