Sounds awesome, I would never think about that. Please check file kernel32\testes\path.c and add some tests to back your changes, at line 1381 you will find the function test_GetShortPathNameW, there is already a extended_prefix test that I think you can duplicate and change. Then read http://wiki.winehq.org/SubmittingPatches
uh, just send the patch, before seeing your reply Since the existing code already strips double path delimiters, but fails to handle this corner case, I felt it was a simple code bug in wine which doesn't need a test case.
oh well, I'll see how it goes. If it gets rejected I'll add a test case and resend. thanks for the pointer on where to add the test.
