In bullet lists, the $around parameter would overshoot. The link would
say around=20, for example, when in fact the correct value would be
around=18. It would add the "* " of the next list item, apparently. The
edit link would still look good because the test we're using is
"$EditParagraphs[0]->[1] <= $pos" -- but if we then don't set "$pos =
$EditParagraphs[0]->[1]" it won't help as we'll get a "Could not
identify the paragraph you were editing" error as soon as we try to edit
with around=20 instead of around=18.
This used to generate an extra entry for @EditParagraphs which in turn
prevented the page from ending with an edit link if it ended with
multiple newlines.
Also made $EditParagraphPencil settable in the config file.
