Merge readline.c r1.106 from NetBSD:
Add trailing NULL's to the varargs functions as required. (John Spencer)
Merge array bounds fixes from NetBSD:
Bounds search for reallocated index, from OpenBSD via Andreas Fett map.c 1.34 map.h 1.10 parse.c 1.27 read.c 1.71
These changes are included in the recent libedit UTF-8 update, but I'm running into these bugs now and would like to get the fix in prior to the MFC.
