There's also /etc/bash.bashrc, /etc/profile, etc. I don't know what's
normal in the mac world. You can try running:

  bash -ix 2>&1 </dev/null | grep LESS

to see what your startup code is doing. I don't know of a good way to
correlate that with the source files, though. Or even to ask bash which
startup files it's looking in.
