* commit.c: Remove defunct variable (got_message).

* edit.c (send_notifications, edit, unedit): Use CVS_LOCK_NONE instead
of 0 in calls to start_recursion to avoid compiler warnings.
* parseinfo.c: Remove duplicate definition of config (from main.c).
* hash.c (walklist): Cast function pointers to void * for tracing.
* recurse.c (start_recursion): Ditto.
