I think the unstated motivation of this choice of the name is to keep the
door open to include lost+found and friends to the repertoire, and perhaps
to have an isolated place for customization for non-POSIX platforms and
for local conventions. It is more like is_uninteresting_dirent_name().
As long as this function is used only to detect and skip "uninteresting"
dirent, I think that is not a bad direction.
On the other hand, I am a bit worried about is_empty_dir() abused outside
its intended purpose to say "this directory does not have anything
interesting". E.g. "Oh, it's empty so we can nuke it":
if (is_empty_dir(dir))
rmdir(dir);
even though the current callers do not do something crazy like this (the
usual order we do things is rmdir() and then check for errors).
