Hey thanks! That's a new one for me, and does indeed look promising.
I've set edebug-global-break-condition to (eq nnimap-split-fancy nil),
and will see what happens. It says it tests the expression at every
"stop point". I haven't explicitly set any stop points; hopefully
they are set automatically, since the whole point of this is that I
don't know where to check for the assignment.
