In a portable script, uncareful use of 'echo' is always insane.

In a script tailored to an environment where echo behaves consistently
it is perfectly reasonable to use 'echo', but that's a different
story.  In the context of git, saying "Here is the thing you should
always use instead of echo" is a good thing, in my opinion.
