Subject: Fix link-rewriting for snippets
X-Git-Tag: release/2.11.58-1~32^2~77
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=02096171dbc22f8a75020cf3be1ae7b5675b677d;p=lilypond.git

Fix link-rewriting for snippets

Since the user_ref_re checks for lilypond(|...), it will also
match lilypond-snippets and thus also rewrite snippets links from
snippet pages, breaking those links.

The workaround is to explicitly match lilypond-snippets and
then exclude those matches in a replacement function.
