e.g a trailing slash changes semantics when dealing with symlinks:

$ mkdir aaa
$ touch aaa/monkey
$ ln -s aaa bbb
$ ls -l bbb
lrwxrwxrwx 1 redi redi 3 Jun 2 18:40 bbb -> aaa
$ ls -l bbb/
-rw-rw-r-- 1 redi redi 0 Jun 2 18:40 monkey

In answer to your first question, I think I prefer (2) too.

Regarding the escape sequence, do you want to play nicely with
null-terminated char strings? If not, '\0' would be my choice, since
that and '/' are the only characters POSIX disallows in a filename.
But there are probably plenty of ways that would cause otherwise valid
programs to fail.

Then again, I'm not sure it's necessary to support slashes in filenames
at all.
