Experiments here show the following (while typing ex-commands manually
in gvim 7.3.390 with GTK2/Gnome2 GUI):

If the GUI is maximized (truly maximized, not just with :set lines=999
columns=9999 but by clicking the Maximize menu or widget), it is
anchored to the screen borders; in that case setting a smaller font will
increase 'lines', 'columns' and also winwidth(0)

If the GUI is not truly maximized, then setting a smaller font will keep
'lines' and 'columns' unchanged and reduce the pixel size of the GUI. In
that case winwidth(0) is also kept unchanged.

Trying to set 'lines' or 'columns' to a value bigger than the available
screen space (also by increasing the 'guifont' size) will cause Vim to
reduce 'lines' and 'columns' to something no bigger than what is now
available onscreen. In this case winwidth(0) may also get reduced.

With no vertical splits present, I always see winwidth(0) == &columns

If you see something else, please answer the following:

- Which GUI flavour? (macvim, GTK2, Motif, Windows, ...)
- Which Vim version and patchlevel?
- Compiled by yourself (from which sources) or downloaded precompiled
(from where)?
- Exact steps to reproduce; actual results; expected results

Best regards,
Tony.
