Attached a cleaned-up patch that combines the essential parts of those commits. With this patch TTY matches more closely with the other backends: even without this in CLX Hemlock C-h and Backspace are distinct -- but our keybindings are (mostly, at least) set up to treat them as identical.

GNU Emacs has the same name, which is a plus. I made some steps in this direction. http://gitorious.org/~nikodemus/hemlock/nikodemus-hemlock/commits/defcomman… Basically: 1. Existing DEFCOMMAND forms work just like they used to, and append -COMMAND to names to avoid need for wholesale renaming. 2. (defcommand ("My Foo" my-foo) ...) uses MY-FOO as the function name. 3. DEFCOMMAND also accepts empty lambda-lists, taking them to mean (&OPTIONAL #:PREFIX). IMO this leads to easier to read command when they don't use prefix arguments. I also went over some exiting commands and made them use the new-style naming: FORWARD-CHARACTER, BEGINNING-OF-BUFFER, etc. Let me know how this looks, -- Nikodemus
