AFAIU, this will avoid Angelo's problem with pinning of Emacs icons
(solving which is probably a Good Thing), but it doesn't resolve the
issues that cause us to have runemacs.exe in the first place.  IOW,
runemacs.exe will still need to be available, even if we adopt this
technique.

Why is this logic needed?  Are there any circumstances where the
pinned icon should invoke emacs.exe, rather than runemacs.exe?
