bug#6385: A slightly less aggressive fit-window-to-buffer

Please post a recipe for reproducing the problem.  I never had any
problem with this in practice so I can't tell.

Let-binding `window-min-height' (I suppose that's the variable you mean)
can be used to make a window less than `window-min-height' high.  Doing
this can eventually cause the deletion of that window after the binding
has been exited.  This is not a speciality of `fit-window-to-buffer' but
a consequence of the fact that Emacs can delete windows that are smaller
than `window-min-height' high.
