FYI, "man echo" on OS X 10.5.5 has this to say...
The following option is available:
-n Do not print the trailing newline character. This may also be
achieved by appending `\c' to the end of the string, as is done by
iBCS2 compatible systems. Note that this option as well as the
effect of `\c' are implementation-defined in IEEE Std 1003.1-2001
(``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for
maximum portability are strongly encouraged to use printf(1) to
suppress the newline character.
Some shells may provide a builtin echo command which is similar or iden-
tical to this utility. Most notably, the builtin echo in sh(1) does not
accept the -n option. Consult the builtin(1) manual page.

Steve.
