The fix to the /usr/bin/keychain shell script worked as shown, but I've added information about where the fix belongs (in the script) later in this message. I suggest correcting the indentations for the proposed fix as needed.

If you don't have to support multiple users (like me), just
downloading the 2.8.0 keychain script to your local path and sourcing
that that in .profile/.bash_profile is probably cleaner.

I seem to notice that keychain 2.8.0 is slower to load than 2.7.1 though.
