Doesn't this work only if the first import in a module fails?
If the second import fails, the parent module name is gone.

On the subject of scripts (though not new in this change), it's a
bit wierd that findPathname() discovers that something is missing,
but then returns its argument intact so that fileInput() will report
the error.  This produces wierdness like a module M matching a file M
with no extension, or the inaccurate message 'Unable to open file "M"'.
Of course fileInput() has to check even if findPathname() succeeded, in
case the file disappears, but earlier on we could give better messages.
