(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.
