I'd love a tiny bit more of information about this :) 

In one of my packages I do some post-processing of a buffer rendered by shr from an html page to increase the font size of a particular title (this is combined with company's support for documentation buffers for completion). 

For this to work properly, I need to ensure that shr does not insert hard newlines to wrap the text; otherwise, the larger sized textx wraps in awkward ways. To do this in Emacs < 25 I set `shr-width' to `most-positive-fixnum' and preprocess the html to remove <table>s and <hr>s (which otherwise cause an out of memory exception due to the `shr-width' hack), and in Emacs >= 25 I set it to 0, which shr seems to recognize there thanks to this test in `shr-fill-lines':
  (if (<= shr-internal-width 0)
      nil

Is there another solution to use visual-line-mode with shr that I have overlooked?
