Thanks, it does. But it produces a different problem:
(expand-file-name "." "c:/foo/bar/") => "c:/foo/bar
(note the absence of the trailing slash).

Sorry, I'm not interested in messing with expand-file-name, as the
gains are insignificant, if there are any, and the potential problems
that could cause are a legion. I actually think that your latest set
of changes there was a mistake (for the same reasons), but as long as
you are prepared to fix the fallout, I won't actively object.
It took us a lot of blood, sweat, and tears to get to the point where
we are: that expand-file-name works correctly for all supported
systems (including DOS/Windows) and also the remote use case. We all
know how one of the gazillion use cases of that function can be easily
broken by a seemingly innocent change in its complex code. So I think
we should leave that function alone, and any problems with file names
(if they indeed are significant) should be fixed elsewhere.
