registry file

Regression (I'm reasonably certain it's caused by
8851a4eb1f51fa56e5ac55d4a1d4a762abb21e3b). I noticed when trying to do
'winetricks mingw'. Winetricks attempts to set the path, using the registry,
and now, crashes:
+ WINEDLLOVERRIDES=mshtml= wine regedit c:\winetrickstmp\path.reg
Warning! unrecognized line:
"

I'll attach the full terminal output and the corresponding registry file.
