This is not going to work until I do something else.  Readline decides
whether or not to append a slash to a directory name, and it doesn't
know that $HOME is a directory name.  This has been the case for as
long as readline has existed.

There's probably nothing in the `ls' compspec to tell the programmable
completion code to attempt variable completion.  You need a
`-o bashdefault' for that.
