Subject: When forming the <A> tag for a \seepep or \seerfc, make sure we strip
X-Git-Tag: v2.1c1~76
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e0197bfaeb4cf189d0a0ee22f52a073c577a0c0f;p=thirdparty%2FPython%2Fcpython.git

When forming the <A> tag for a \seepep or \seerfc, make sure we strip
HTML markup from the string used as the title in the TITLE attribute.

This fixes formatting in the "What's New in Python 2.1" document.
