If you're planning to filetest the return values out of a
"readdir", you'd better prepend the directory in question.
Otherwise, because we didn't "chdir" there, it would have been
testing the wrong file.
opendir(my $dh, $some_dir) || die "can't opendir $some_dir:
$!";
@dots = grep { /^\./ && -f "$some_dir/$_" } readdir($dh);
closedir $dh;
