I don't know why {} works in Win32 Gvim. I don't really have time to
figure it out. Perhaps someone else can dig into the code.

This is documented: A full match is preferred over a partial match.
Internally the ^ and $ are added to find a match, only if this fails
they are left out. Thus if you _only_ want to find a full match you
should add the ^ and $.
