There are licensing issues: libreadline is GPL, and you probably don't 
want liblua and anything that links to it to be covered by GPL by 
default. Maybe an interface similar to `lua_setallocf()` would be 
possible. Then the host application (e.g. the Lua interpreter) can link 
to libreadline if desired and provide the necessary function pointers to 
have line editing in `debug.debug()`. Depending on how popular 
`debug.debug()` really is (I think I've never used it) this might be 
overkill though.
