[PATCH 5/9] CMD: echo command needs to ignore whitespace

[Jason Edmeades]

Reported problem is "echo on > file" echos the word on to the file,
but the underlying issue was any whitespace around the 'on' word
caused problems. This patch ignores whitespace and handles the case
where the first word of a sentence is on or off.

Fixes bug 21132

Note: Be aware this patch adds whitespace to the end of some of the
test cmd lines, so please do not strip whitespaces from this patch!!!
