Works surprisingly well out of the box.
There seems to be a problem in some cases with foldtext returning a line
of dashes¹, the pattern seems to be the presence of a leading blank on
the first line of the section - ' 1. section' vs. '1. section'.
So it looks like I will have to take a closer look at foldtext, and if I
can figure it out, 'amend' it. :-(
But thanks for your advice, it appears to work about nine time out of
ten, which I find really useful - and much cheaper than Amazon's Kindle
for the long winter nights. :-)
Thanks,
CJ
¹Actually, removing the foldtext modeline makes the content of the first
line reappear, though not with the best of formatting.
