Another one for gnu.bash.ufo:

Scenario: am in GNU emacs, and type the C-@C-uM-| invocation that results in
running a command in a subshell and replacing the currently selected piece of
text with the result.  Much to my surprise, a "You have mail in ..." string
appears in the output, which I can only attribute to bash being silly or to
some rather interesting file descriptor mix up.  Does bash really check for
mail in non-interactive shells???
