For you, instead of patching dmenu it will be much better to just check
it input is only one line. If it is, then there's no reason for you to
fire-up dmenu.

Any such patch to dmenu you are suggesting is imho big NO-NO. Afterall,
you wan't be able to change that command, add/remove some arguments etc.
Also, what's such bad on user pressing enter after possible some change?
