* gdb-events.sh: Make if statements and tests

	a little more portable.
	Don't use shell's echo command to put strings containing
	escaped characeters into a file -- different flavors of /bin/sh
	require differnt levels of escaping. Use cat <<EOF instead.
	Our internal field separator is a colon. Change all
	commands which assume it is a space.
