Setup: weechat running in tmux on a server, user connects via ssh and attaches
to tmux, terminal is urxvt
When pasting 14 lines to urxvt/weechat the terminal correctly asked if it’s
ok to paste 14 lines, but weechat only asked about 8 lines.
This could be circumvented once by enabling the weechat.look.paste_bracketed
setting, but failed again after one successful paste.
Weechat gets all 14 lines when run locally, i.e. not via network.
