Sorry, my bad, I've left an unused variable in the patch.

I initially  thought it would be nice to report errors when the
file cannot be read in $mapfile[file], but then gave up on it on
the ground that it was not done with mmap().

Now maybe it would make sense to report errors other than ENOENT
here (even for the open)?

But then that could become annoying for things like
(($+mapfile[somefile])) (not that people should use that).
