Re: New keybinding suggestion: C-x _ for `shrink-window'

[Richard Stallman]

Lennart Borgman has been working on a similar package, now called
winsize.el, which is implemented using the ordinary command reader
with a special keymap.  That's the basic difference between these two
packages.

If it is now clear that using the ordinary command reader is the best
approach, we may as well go with winsize.el.
