And if this change does introduce some kind of valid breakage, it would be nice to know about this sooner rather than later. I know 26 is already in beta, but this is essentially a bug fix and the recent patch is also smaller and more clearly laid-out which makes it easier to assess and reduces its side-effects. > Btw. Lars. Mentioned a hang. I have also got a hang a few minutes ago reading > nntp news with an specific site Do you get those hangs with an Emacs version that had the bug fix? And have you been able to pinpoint where exactly Emacs hangs? (backtrace) Also, is this a "cancelable" hang (hitting ctrl+g) or a real hang and you need to kill Emacs altogether?
