This is a follow up question from Box highlighting of text with rounded corners (soul-based). The desired end result is a sort of "circled text", as one would do if annotating a text with a pencil.
I answered that question myself, based on Antal Spector-Zabusky's approach in Cool Text Highlighting in LaTeX. The result is cool enough, but one important limitation is that it does not allow for page breaks. It doesn't because the approach relies on soul for providing coordinates and lets tikz do all the drawing. That was needed in Antal's answer because the desired irregularity of the path, to make sense in a drawing, depended on the decorations from tikz.
Well, I'm looking for something "less cool" and would be satisfied with straight lines above and below the text. And for that, I could rely on soul rather than tikz to draw them, thus retaining page breaking capabilities. And then, use tikz to draw the corners only.
I started from the same idea, but tried it from scratch, based on the soul driver for \ul. The code below gets close, but not quite. I cannot convince \SOUL@everyspace to draw the line above as well.
The crux of the matter seems to lie in:
\def\SOUL@tceveryspace#1{%
\SOUL@ulcolor{
#1%
\SOUL@tcleaders
\hskip\spaceskip
}%
\null
}
where \SOUL@tcleaders does the actual drawing with an \hrule:
\def\SOUL@tcleaders{%
\leaders\hrule\@depth\SOUL@tcdp\@height\SOUL@tcht\relax
}
Is there a way to draw both (bottom and top) hrules in this step?

The result thus far is:
That is, everything is in place, except the lines above the spaces. Any ideas on how to get them?
souldriver for underlining, I just adapted it. – gusbrs Apr 17 '18 at 15:58current page text area(tikzpagenode package) in the case of a page break? – Apr 17 '18 at 16:27soul. How could we decide on the fly when not to do it and use insteadcurrent page text area? Or am I missing something from your suggestion? – gusbrs Apr 17 '18 at 16:41current page text area, whatever comes first. One possible way to achieve this is to run a white line from the corners to the boundary ofcurrent page text areawhenever you issue the closing brackets. – Apr 17 '18 at 16:57
