Ok, I didn't know about that functionality. One possibility would be
to make fish_title always set the screen title instead of the xterm
title when inside screen. Would that make sense?
Other than that, I suspect that the bell you hear is because the bell
character is the end of the escape code for setting the title. So make
sure that at the end of the title, the beginning but no the end of the
set tterminal title escape sequence has been set. Something like this
might work:
function fish_title
echo -ne \7\033 blah blah screen title\033\e]2\; blah blah xterm title
end

None. The reason why that exists is:
* Because everybody but me seems to like it. I hate it, but I am weak
and want people to like me.
* Because it expands differently, specifically quoted variables are
expanded to exactly one element, even if the variable is an array. The
elements are space spearated. This is often useful, for example when
using a variable in test you generally want to be sure of how many
arguments are created from a variable expansion.
