As it seems, the initial version of the patch didn’t play well
	with other essential shr.el features (as in: hyperlinks.)

	Please thus consider the revised patch MIMEd.

	* lisp/net/shr.el (shr-force-fill): New variable to disable this
	feature if needed.
	(shr-internal-width): Defer initialization until...
	(shr-insert-document): ... here; set to nil if neither
	shr-force-fill nor shr-width are non-nil.
	(shr-fold-text, shr-tag-table-1): Likewise.
	(shr-insert): Do not fill if shr-internal-width is nil.
	(shr-setup-wrap-1, shr-setup-wrap): New function.
	(shr-tag-blockquote, shr-tag-dd, shr-tag-li):
	Call shr-setup-wrap.
	(shr-tag-hr): Use a constant if shr-internal-width is nil.

	The other so far unresolved issue with this approach is that the
	tables and <pre /> elements may actually require truncate-lines.
	Unfortunately, I know of no way to allow for word-wrapped and
	truncated lines to exist in the same buffer; I guess we may need
	either a truncate-lines or word-wrap property (or both) to
	override the buffer-local variables in this case.

	Similarly to wrap-prefix, we may also use line-prefix in place
	of shr-indent.  But that may not be a good idea if quoting
	text/html messages in text/plain replies, for instance.
