I kinda wanted to keep the HTML files and the results as close to the
input/output from eww as possible.  That is, you can just say `M-x
eww-open-file' on the HTML test files and twiddle the shr code until it
looks right, and then you copy the output to the .txt file.

That's a really convenient way to create the regression test cases.

Yeah, the files do not survive editing with those values.

I've never played around with local variables in text files.  Can these
local variables be put into a dot file of some kind?
