And only allows glob matches on filenames ... enuf for this case though.

BTW: WARNING.

When converting code to the new format BEWARE:

	union X = | NIL | A of X*X;

	match x with
	| A (_, NIL) => ...
	..

This won't work as you might expect because in that pattern NIL is a variable.
Easy to miss. You have to write

	| A (_, #NIL) => ..

to tell the parser the NIL is a type constructor.
