	basesrc/bin/sh: sh.1 trap.c

Log Message:
Extended functionality of the trap builtin, which now closely follows
POSIX recommendations.

	- trap now accepts signal names and signal numbers
	  e.g. INT, SIGINT, 2
	- added option -l that outputs a list of valid signals
	- added signal EXIT to list of valid signals
	- a `-' in the action part will reset specified signal to their
	  default behaviour
	- changed standard output format to make it suitable as an input
	  to another shell that achieves the same trapping results
