Subject: doc: improve the echo and printf help on escapes

* src/printf.c (usage): Merge strings with echo.c to
aid translators.  Move the description for \NNN beside
the other numeric escape codes.  Don't mention
"character" as that suggests character conversion.
* src/echo.c (usage): Likewise.
Also mention the \xHH escape sequence.
