Okay so it's a feature then... I just couldn't imagine this to be a
useful feature :-). That's fine though, I'll just disable modelines for
files that try to set the 'lines' and/or 'columns' options.

Utmost caution should be exercised when setting a global option via a
modeline. It will affect all others buffers and windows, which won't
know about it and therefore won't take appropriate countermeasures when
they next come into focus; and it may have undesirable effects when run
in an environment other than your usual. For instance, if someone tries
to open a file, whose modeline sets 'lines' and 'columns', in a Vim
instance running in a fixed-size terminal (e.g. an 80x25 "hardware-text"
console), the most likely result (which I've seen happen) is that Vim
won't know that the resizing didn't work, and parts of the Vim screen
(including the statusline and command-line if 'lines' were increased)
will be cast off the right and bottom edges of the physical screen.
I can imagine that there are uses for setting global options via
modelines, but they are few, far between, and fraught with more pitfalls
than is good for anyone's health and sanity. If Bram decided to totally
disable global options in modelines, I for one wouldn't complain.
Best regards,
Tony.
