I'm still unsure of the size calculation for the path. You're adding 2
characters, but afaict it's only to account for a single backslash.
I'm signing off anyway because being too cautious by one character in
the filename seems acceptable to me. The tests pass using wine-mono
from the master branch, and it looks correct to me otherwise.
