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.
