dexen hits the nail on the head right there... files and directories
could be contextually distinguished from each other by always specifying
the directory name with a trailing "/".
"foo.c/" means the directory foo.c/.
"foo.c" means the file ./foo.c
There's no way that I know of to possibly interperet a path ending in
"/" as a file (with the exception of reading raw Dir data, as on Plan
9 or "cat /" on, what was it, Solaris?).
