Module Name:
Omikron.cpp
Abstract:
Shims RegQueryValueExA so that when the app asks for the shell command
for opening an rtffile, it gets what it expected to see under Win95:
"C:\WINDOWS\WORDPAD.EXE %1" This is, of course, wrong, but we then apply
CorrectFilePaths, so when it actually goes out to launch wordpad, it has
the right path.
This is necessary because it can't have a path name with spaces in it
Notes:
This is specific to Omikron.
