Subject: rewrite_descriptor():  Fixup conversion of arguments (simpler).
X-Git-Tag: v1.6a1~712
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=645af9fedd52b2ca1d96992ff63e3a8255a869c3;p=thirdparty%2FPython%2Fcpython.git

rewrite_descriptor():  Fixup conversion of arguments (simpler).

join_adjacent_elements():  Hack to merge adjacent instances of
        <option>; the source \programopt with GNU-style long options
        created problems with LaTeX2HTML; this removes the evil
        workaround, which should never be necessary from structured
        documents(!).
