This looks good now.

I am not entirely sure why that happened, but cleanpath/cleanstr had an
off-by-one error. This

    while (e != path && (*e == sep || isspace(*e)))

should be 

    while (e >= path && (*e == sep || isspace(*e)))

i.e. we should enter the loop body for e == path, too, so that we reduce
the string "\n" to ""
