Perhaps extend this thus, and handle multiple slashes?

Sure, it could be done. But the reason why I didn't do that myself was
that I got a bit worried about this being a slippery slope towards
full path-normalization. FindFirstFileA() does handle non-normalized
paths, as long as they are below MAX_PATH in length.

I just didn't want to add a slash if there was already one there,
which is something different than trying to fix the input-path.

In other words, I'm not entirely sure if fixing up such a case is a
task that belongs to opendir.
