Yes, but I was not having trouble with just '\n' before, and the pattern
did match in Kodos, so I figured Python was doing its newline magic like
it does with the write() method for file objects.
http://x264.nl/x264/64bit/8bit_depth/revision[\r\n]{1,3}[0-9]{4}[\r\n]{1,3}/x264[\r\n]{1,3}.exe
does indeed match. One thing that confuses me, though (and one reason I
dismissed the possibility of it being a newline issue): isn't '.'
supposed to not match '\r'?
