According to POSIX, appending a trailing '/' requires that a name be
resolved as a directory (either an actual directory, or a symlink to a
directory).

'/' is never a final component (except for the root directory '/' where
it is the only component). In POSIX parlance, a final component is
determined by stripping trailing slashes (except for the special case of
the root directory), then using the non-slash portion after the last
remaining slash. However, the mere presence of a trailing slash does
affect resolution rules, in that the component being resolved has to be
a directory or a symlink to a directory.
