After having understood the following documented behaviour:

"An RE consisting of two or more branches connected by the | operator
prefers longest match."

and having looked very hard at {^|(.+?)|}, I have trouble combining the
two, without arriving at a conclusion as to what it should do.

So, unexpected? ... no, not yet; mainly headache and inconclusiveness.

Thanks for the riddle ;-)
