The one thing I always add to my profile is "export COMMAND_MODE=unix2003". This will make some commands behave as you would expect them to under Linux instead of BSD.

Don't recall seeing that in my brief scan of the dotfiles.

For the record: COMMAND_MODE=unix2003 is already default in Terminal(.app), but it should definitely be set for iTerm.
