Actually a lambda is already supported, so no changes are required.

A special case for fit-window-to-buffer, shrink-window-* and other similar
could be implemented only when you are sure that a `window-min-height' entry
is not going to be used for other purposes besides of using it as an argument
of a window-height entry.

BTW, fit-window-to-buffer has also other arguments: MAX-WIDTH and MIN-WIDTH.
Would they be useful for a window-width entry?

This is very much needed, thanks.
