	This also makes sense, indeed.  Perhaps we should either provide
	yet another user-settable option for that (what about
	eww-default-uri-hook – to be run -until-success – for
	instance?), or provide /two/ separate commands for these two
	behaviors.  Or even three, as it’s perfectly possible to stumble
	on the case where the text under point is a valid URI, but lacks
	an associated shr-url property (think of browsing a text/plain
	Web page, for instance), or has it different to the text itself.

	The eww-default-uri-hook solution seems reasonably easy to
	implement; I hope to suggest a possible patch later.
