Bug#903736: latex2html: Unescaped left brace in regex is deprecated

[Niko Tyni <ntyni@debian.org>]

Package: latex2html
Version: 2018-debian1-3
User: debian-perl@lists.debian.org
Usertags: perl-5.28-transition

While test rebuilding the archive against Perl 5.28 (currently in
experimental), we noticed these warnings in the build log of this package:

  Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^([^{]*){ <-- HERE / at ../latex2html line 1901. 

  Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.32), passed through in regex; marked by <-- HERE in m/\s*({ <-- HERE |})\s*/ at /<<PKGBUILDDIR>>/styles/graphics-support.perl line 175, <STYLES> line 2.
