Subject: texi2html: Fix the parent detection of the TOC for unnumbered sections
X-Git-Tag: release/2.11.58-1~32^2~99
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=2faa5a9de6d10bb655d59312257777b74258afd7;p=lilypond.git

texi2html: Fix the parent detection of the TOC for unnumbered sections

Instead of using the section number I'm now using the ID of the sections
to properly detect parents of the current page even if we only have
@unnumbered sections (as compared to @chapter). This fixes the snippets
page.
