Thanks; I pushed the first hunk.  I didn't push the second one because
I don't think it's required.  If you disagree then make your case ;-).

Thanks for the patch!

P.S. Overly-literal-reading corner: doesn't "All characters following...
will be ignored" mean that «echo 'foo\cbar' 'baz' 'qux'» should be
equivalent to «echo 'foo\cbar' '' ''»?  I.e., print «foo» followed by
two trailing spaces?
