echo vs. printf regression (darwin8)

[David Fang]

Hi,
	The ECHO that is chosen by autoconf on darwin8 (printf %s\n) is 
buggy:

fangism % printf %s\n foo
foonfangism% printf '%s\n' foo
foo

Must be due to the version of the Bourne shell (2.05b).
Failure is similar with sh-3.2.
The 'correct' value of ECHO should be printf '%s\n' (note the extra 
single quote protection).
I don't know yet whether that is forward-compatible with newer versions of 
Bourne shell.

Don't recall which version of autoconf broke this, betweem 2.63 and 
latest.
