This probably depends somewhat on your platforms choice of behaviour for the
ANSI C 'remove' function. On the Acorn, it does indeed remove the directory -
as long as it is empty... occupied ones are a different matter!

It's also a poor implementation - it opens the file and immediately closes it,
instead of using a more efficient OS call.  A prim would be much better.

I'd say that would be reasonable. Just as long as the SQ code can cope properly
with older VMs missing the prims...
