In my experience 'with-selected-window' is bad because any functions its
body calls cannot tell whether the selected window is the "real selected
window" and its buffer the "real current buffer" at that time.  A
typical example is 'mode-line-format': users who wanted to paint the
mode line of the selected window in some special way could not do that
because they could not tell whether that window was the real selected
one.  If such issues are of no concern, use 'with-selected-window'.
