NAME
	echo - print arguments

SYNOPSIS
	echo [-n] [arg ...]

DESCRIPTION
	Echo writes its arguments separated by blanks and terminated by a
	newline on the standard output.  Option -n suppresses the newline.

so says the plan 9 manual, and therefore it must be the right thing :-)

[before anyone gets on my case that es' echo has one extra option already,
--, and therefore is not plan 9 compatible, i'm just going to defer to
Byron's historical practice in rc and say i like that a lot.]
