Similarly, PWB/CB-UNIX/SysIII echo exists as printf %b
("XSI" is a stand-in for "alas, SysIII-and-friends do this
and we ratified it when the standard was just XPG/SUS"),
and the standard encourages you to Not Use echo at all ‒
if there's backslash-escapes they /may/ get intepreted too!
For echo use printf %s\n, for echo -n use printf %s,
for SysIII-style echo-with-escapes use printf %b\n
(or convert to a native printf expression).
The only thing echo makes sense for is to Just Write A New-Line
