m4sugar: factor away _AS_ECHO_PREPARE.
"printf '%s\n' ..." has been a fine replacement for plain "echo"
for at least 5 years (probably more like 10), even with most
museum-piece shells.
* lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Remove.
(_AS_SHELL_SANITIZE): Keep as_nl setting originally from
_AS_ECHO_PREPARE here where it more properly belongs.
(AS_ECHO, AS_ECHO_N): Use printf unconditionally.
* doc/autoconf.texi (Limitations of Shell Builtins): Document
preference for 'printf' over working around 'echo' bugs.
* NEWS: Updated.
