I'm back on my dev machine (~, sweet ~), so I can answer this better now.

Look at the terminal_size function. It's a DEFUN in src/pager.cc, and
usually is just a wrapper to GNU readline, which it uses to gather
information.

Now look at src/pr-output.cc, which has most of the logic for how to
split lines and print other things. You'll notice it uses
command_editor::terminal_cols (); in some locations to determine
screen width, which is the same as what the terminal_size function
above uses. If you look at cset 13112:969ed305dde5, you'll see other
locations I had to patch in order to affect display of some things:
