/*
 * ex_map -- :map[!] [input] [replacement]
 *	Map a key/string or display mapped keys.
 *
 * Historical note:
 *	Historic vi maps were fairly bizarre, and likely to differ in
 *	very subtle and strange ways from this implementation.  Two
 *	things worth noting are that vi would often hang or drop core
 *	if the map was strange enough (ex: map X "xy$@x^V), or, simply
 *	not work.  One trick worth remembering is that if you put a
 *	mark at the start of the map, e.g. map X mx"xy ...), or if you
 *	put the map in a .exrc file, things would often work much better.
 *	No clue why.
