Thanks! I never would have thought of that. (Why isn't this mentioned explicitly
in the manual?)

Unfortunately, passing this regexp to `flush-lines` or `kill-matching-lines` in
a file of close to 65000 lines completely cripples Emacs... One CPU core runs up
to 100% and Emacs becomes unresponsive.

Lemme see if a function that goes through the buffer, splits every line on white
space and deletes those that are too long works better.

Thanks, though, for the quick reply!
