That line width should be based on a pixel width (1024 is probably
reasonably).  It is nonsensical to have it based on a paper size.

I don't think that we should "fall back".  When generating HTML, we
should not consider paper widths at all.

If lilypond-book calls texi2pdf in the course of generating HTML, that
is a bug.

Sure, that too.  lilypond-book needs to figure out the paper width when
generating PDF via TeX.  Whatever is needed for that is needed.  But for
the HTML docs, nothing from the TeX toolchain should be required.
