Provide a DEFAULT argument in #'intern-soft. 2007-12-24 Aidan Kehoe <kehoea@parhasard.net> * symbols.c (Fintern_soft): Provide a new optional third argument, DEFAULT, for those who want to check if "nil" is a symbol or not. (More realistically, general code that may get handed "nil" should probably use this argument.) * keymap.c (define_key_check_and_coerce_keysym): Call Fintern_soft with its new argument. * lisp.h: Update the declaration of Fintern_soft.
