Don't use 'echo'; use 'printf %s'.

I didn't write this code (as the comment says) but I /thought/ that
the whole point of it was to autodetect if echo -n worked, and if so
use it because it'd be faster than printf "%s", otherwise use some
evil foo\n\c hack.

That hack doesn't work on bash ('\c' produces a space), maybe it
doesn't work anywhere. Do you have a shell that doesn't support echo
-n? What does it output there?

I wouldn't be surprised if it did need to be changed to printf
"%s". I'm just curious where it broke and how.
