Use printf rather than echo -n.

On AIX, there is no -n option to the system's echo.  Instead,
it needs the '\c' control character.  We could replace
  echo -n "foo"
with
  echo -e "foo\c"
but printf is recommended by most man pages.  Tested on AIX
5.3, Solaris 8, and Debian.

[jc: futureproofed two instances that uses variable with '%s'
 so later feeding different messages would not break things too
 easily; others are emitting literal so whoever changes the
 literal ought to notice more easily so they are safe.]
