That kind of thing will be cleaned up before committing (I'm not
entirely sure how one goes about adding default bindings).

[I think the C-+/C-= and C-- bindings are correct however, as they are
what people expect.]

I did, though the mechanism was quite different.

The current code operates _per buffer_ (the previous code grew or shrunk
the entire frame).  I think per-buffer operation is far more useful
(e.g., I currently have my Gnus article buffer resized up one step which
is kind of pleasant; for viewing big files, resizing down a step or two
is quite nice).

The size calculations I'm using are the same as before -- a simple
constant factor height scaling for each step -- and probably will
occasionally miss a step on platforms with only non-scalable fonts and
poor font size coverage.  With scalable fonts, however, this simple
calculation works very well.

[Another issue with per-frame size changing was that very frequent
changing of the default frame face tended to crash Emacs.  The whole
baroque mechanism that gets invoked for that case is complicated and
fragile.]
