doc: remove extra quotes in generated docs

Commit a38edab7c8 (Makefile: generate doc versions via GIT-VERSION-GEN, 2024-12-06) moved these variables from the Makefile to asciidoc.conf.in. When doing so, some extraneous quotes were added; these are visible in the generated .xml files, at least, and possibly in other locations: --- a/tmp/orig-git-bisect.xml +++ b/Documentation/git-bisect.xml @@ -5,14 +5,14 @@ <refentry lang="en"> <refentryinfo> <title>git-bisect(1)</title> - <date>2024-12-06</date> -<revhistory><revision><date>2024-12-06</date></revision></revhistory> + <date>'2024-12-06'</date>^M +<revhistory><revision><date>'2024-12-06'</date></revision></revhistory>^M </refentryinfo> <refmeta> <refentrytitle>git-bisect</refentrytitle> <manvolnum>1</manvolnum> -<refmiscinfo class="source">Git 2.47.1.409.g9bb10d27e7</refmiscinfo> -<refmiscinfo class="manual">Git Manual</refmiscinfo> +<refmiscinfo class="source">'Git 2.47.1.410.ga38edab7c8'</refmiscinfo>^M +<refmiscinfo class="manual">'Git Manual'</refmiscinfo>^M </refmeta> <refnamediv> <refname>git-bisect</refname> Signed-off-by: Kyle Lippincott <spectral@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
