I don't know of anything analogous to `shrink-window-if-larger-than-buffer'.

However, you can use `C-x {' (`shrink-window-horizontally').

To repeat it (to use it incrementally), either bind the command to a repeatable
key or use `C-x { C-x z z z z z'...

You might also be interested in `face-remap+.el'. It recuperates wasted
horizontal whitespace that results from shrinking text, by shrinking the window.
(It can also do the same thing for wasted vertical space.)
