Modified Files:
	basesrc/bin/sh [netbsd-1-5]: trap.c

Log Message:
Pull up revisions 1.25-1.26 (requested by jonb):
  Extend functionality of the trap builtin, which now more closely
  follows POSIX recommendations:
   o accept signal names as well as signal numbers
   o add ``-l'' option which outputs list of valid signals
   o add signal EXIT to list of valid signals
   o an ``-'' in the action part will reset signal to default behaviour
   o changed standard output of ``trap'' to make it suitable as
     subsequent input
  Also various cleanups of redundant declarations and nested externs.
