I know, sorry about that, but in the wine-patches archives there appears to be an extra space
amstream/ - MultiMedia Streams + atl/ - Active Template Library avicap32/ - AVI capture window class
but if I do the diffing on my pc I don't get this. But patching works with both your patch, that appears to have the extra space, but doesn't, and with my patch that doesn't appear to have an extra space. I have of what is going on. BTW the patch that I sent was edited manually, so had a missing space at every added line.
It looks odd because the existing lines have tabs, but the added lines have 8 spaces instead.
