I don't consider ansi-term to be "unrelated" to shell.el, so I think
it's perfectly OK for it to (require 'shell).  It might even encourage
more sharing of code between the two.

For `dired-insert-directory`, I'm not sure whether it's better to use
bound-and-true-p like we do now or to use something else entirely.
IOW, I'm not completely sure why it uses `explicit-shell-file-name`
instead of `shell-file-name`.

But, it's clearly OK to leave the current dired code as is.
