Bug ID: 44133
           Summary: cmd.exe does not accept space after drive
           Product: Wine
           Version: 2.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Consider the following script run directly in cmd.exe:

C: & echo 1

This yields

Can't recognize 'C: ' as an internal or external command, or batch script.
    1

while it should instead switch to drive C:. The origin of such code is
luarocks: it is how it executes command in specific directory.

Wine version used is 32-bit wine-any-2.19 from Gentoo portage on a 64-bit
multilib system, USE="X alsa cups fontconfig gecko gstreamer jpeg lcms mono
