Full path to wine executable in generated .desktop files

[Ilya Basin]

When you install a program, some desktop files are put here:
~/.local/share/applications/wine/
~/Desktop/

  [Desktop Entry]
  Name=Microsoft Office Access 2003
  Exec=env WINEPREFIX="/home/leniviy/.wine" wine ...

I have 2 wine instances: official in /usr and patched in
/opt/wine-csshack . Because of that I would like to have
"/opt/wine-csshack/bin/wine", not just "wine" in the generated
.desktop files.

What can go wrong if we do so?
