The change in behavior is unconditional, AFAIU.  Should we have a
separate knob for that?  Perhaps someone out there doesn't want text
to be indented when shr-fill-text is nil?

Also, please time the code on some substantially large body of text,
with and without shr-fill-text, and compare that with the current
version.  I think performance is an important aspect of any change in
this area.

Thanks.
