But there's much more in a shortcut than there is in a symbolic link.

Really?  I thought they used their own mechanism to simulate symbolic
links on Windows.  A Cygwin symlink file (created by "ln -s") even has
a magic number ("!<symlink>" IIRC) which is not Microsoft's style.

Do you know what the format is?  Or which MFC call is used to
determine that the file is a shortcut and read the referred to file?

Actually, if it can be parsed and because there is much more in a
shortcut than just a pointer to a file (type, location, where to
start, how to run, shortcut key, etc.), I think it would be better if
Emacs had a shortcut-mode which would parse the binary, display the
results in text, and allow (careful) editing of the information.
