--- Comment #9 from Colin Fletcher c0l1n_fl3tch3r@yahoo.co.uk 2009-10-13 08:49:47 --- Created an attachment (id=24076) --> (http://bugs.winehq.org/attachment.cgi?id=24076) Patch to make cmd treat tabs as spaces in batch file parameter lists.
Here's a (pretty trivial) patch to treat leading and trailing tab characters in batch file parameters in the same way as spaces.
With this patch applied, output from test.bat under wine cmd matches the output under XP and Vista.
