I believe that /bin/echo and the bash built-in used to be slightly different,
although reviewing both man pages on my FC5 system seem to indicate that they
have the same command-line arguments.

It's also possible that I'm thinking back to my Solaris (2.5.1) days when the
built-in tcsh echo was in fact different than /bin/echo.  That's why all my
scripts seem to call the binary and not the built-in.

Another possibility is that the original author had the options set in his
xpg_echo environment variable and forgot about it...or his distro was setting
it in a profile.d file.
