(info "(elisp) Directory Names" says to use:
(concat DIRNAME RELFILE)
So if I'm iterating thru a path that is defined to contain directory
names (as `load-path' is, but see other email), this code is correct:
(concat dir name)
However, if the path contains directory file names (as
`load-path' is implemented), then this code is correct:
(concat (file-name-as-directory dir) filename)
However, `file-name-as-directory' tolerates ending slashes or not in
`dir', so the latter code is robust against people putting the wrong
things in the path.
Same for `expand-file-name' of course.
