bug#55169: Can't combine window-min-height with window-height

It introduces a certain inconsistency.  So far, 'window-min-height' is
obeyed by 'display-buffer-below-selected' only.  My patch would have
other clients obey it as well - but to a certain extent only.  For
example, 'split-window-sensibly' will never care whether a window it
splits off can be made 'window-min-height' lines high.  How would we
document that fact?
