Just to not leave this unfinished, here the last patch I did which
simplify code.
- defcustom is simple (string or nil).
- No need to reevaluate defcustom at every time.
- setq is usable.
- splitting is now simple with all the text property dance removed.
- plain string is added to history instead of a crap string.
