because it is compared against "IP=127.0.0.1:<port>"
where <port> is generated by the OS. In this case
you'd need some
where the "IP=" and the ":<port>" portions get
stripped. Note that also some "children" and
"subtree" styles could be useful: in the above
reported case, an hypothetical
would do the trick without using regexp at all.
I recall this issue being discussed some time ago,
to no extent.
