Please avoid modal UIs wherever possible.  E.g. rather than ask with
yes-or-no-p, just choose one of the two branches (maybe based on
a config var) and output a message explaining how to get the
other branch.

Hi all,

this patch fixes the inconveniences Reiner pointed out in #3865.  Could
somebody please commit it for me on branch and head?

I'm to busy to read up how to merge between branches with CVS -- I'm
going to marry tomorrow! :-)

	* doc-view.el (doc-view-initiate-display): Add yes-or-no-p if
	rendering of pngs is not possible instead of messaging a long
	description.
