Indeed, echo seems to have been changed after the 5.2.1 release (I tested
with 5.3.0).  Printf behaves as I described even in 5.2.1, though.

Not quite, since it doesn't handle these cases:

%/usr/bin/echo -e 'a\c' b
a
%/usr/bin/printf '%s\c%s' a b c
a
%/usr/bin/printf '%b %b\n' a b 'c\c' d e
a b
c

I've attached an extended patch that should do this.
