When trapped in a web, trying to move while wielding Sting gives the
message "Sting cuts through the web." In 3.6.1 and earler, that
also released you from the trap, but with 3.6.2-beta nothing happens.
It had nothing to do with the recent web spinning patch. My change
to have being trapped block levitating and flying included replacing
a lot of direct manipulations of u.utrap with set_utrap() and
reset_utrap() in order to keep the lev/fly blocking and unblocking
localized. Unfortunately, the old 'u.utrap = 0' when wielding Sting
while stuck in web was deleted in error at that time.
