--- Comment #2 from Franc[e]sco lolisamurai@tfwno.gf --- Created attachment 68141 --> https://bugs.winehq.org/attachment.cgi?id=68141 patch that fixes the issue
this patch fixes the issue by stopping quote counting at & in WCMD_IsEndQuote however I'm not 100% sure this won't break other stuff as I'm not familiar with wine's cmd parsing code
