Re: w3m-popup-buffer problem



TLDR; Although the bug had been reproducable, since performing `make
install' and killing all emacs processes, the bug hasn't been
reproducable. The remainder of this response is to record the issue in
case it does happen again reproducably.

Here are some possibly relevant variable settings:
+ w3m-use-tab is a variable defined in ‘w3m.el’. Its value is t
+ w3m-pop-up-frames is a variable defined in ‘w3m.el’. Its value is nil
+ w3m-pop-up-windows is a variable defined in ‘w3m.el’. Its value is t
+ w3m-new-session-in-background nil

Now, no longer necessary.

My guess is that the abundance of frames were probably created when an
outside script repeatedly ran `emacsclient --eval "(browse-url
\"$1\")"'. However, now even that is no longer reproducible - ie.
repeatedly invoking the script doesn't increase the number of frames to
more than two, per evaluating (frame-list) and (visible-frame-list).
