Seems okay to me... "which which" says it's a built-in. Correct.

"/usr/bin/which which" doesn't know about built-ins, so it finds
/usr/bin/which. Maybe not exactly correct, but okay.

"which -a which" runs the csh builtin "which," which doesn't claim to
support the "-a" option. See the csh(1) manpage. It's /usr/bin/which
that takes the "-a" option. No problem there.

"/usr/bin/which -a which" returns /usr/bin/which.
