Well, ``return 0'' and ``fails'' are not exactly the same.  The
original complaint by Juanma was that a non-zero status was returned.

Anyway, I see now that I missed something important: we already have a
wrapper for spawnve (w32proc.c:sys_spawnve), and it already tries to
quote arguments.  In addition, it invokes the command thru cmdproxy.
So somewhere between the quoting code and cmdproxy there's a bug that
causes `find' to not find anything.  AFAICS, quoting *.el with
shell-quote-argument causes it to wind up quoted in `find's argv[]
array, which explains why it finds nothing.  Someone(tm) needs to
debug this.
