Clear away all aliases for interactive shells
Some systems like OpenBSD or Slackware set up well-meaning aliases that
I don't want.
We do this for Bash, Yash, and Zsh, but not for Ksh, because it looks
like its implementations all variously use aliases to implement some
POSIX builtins like fc(1) or type(1) in terms of their own builtins.
