Thanks for working on this.

That's a good transition strategy at least.

As long as we aren't switching over completely, we don't benefit from
M-. on command names as written, but I guess that's okay for now.

One thing to keep in mind though is that sometimes we need to find
command function names from the command.

The two function I can find which currently rely on the -command suffix
are:

  - edit-command-definition

    M-. replacement for command names

and

  - find-command-for-prepl-normally

    which makes it possible to run commands like
       CL-USER> ,start-slave-process
    or
       CL-USER> ,dired "/etc"
    in the repl.

How would be fix them on the branch?

Nice.
