# Fix a problem with HTML output produced by makeinfo 4.8.
#
# groff.texinfo uses (after macro expansion) something like
#
# @deffn ...
# @XXindex ...
# @deffnx ...
#
# which has worked with earlier versions (using an undocumented feature
# of the implementation of @deffn and @deffnx). Version 4.8 has new
# code for generating HTML, and the above construction produces wrong
# HTML output: It starts a new <blockquote> without closing it properly.
# The very problem is that, according to the documentation, the @deffnx
# must immediately follow the @deffn line, making it impossible to add
# entries into user-defined indices if supplied with macro wrappers around
# @deffn and @deffnx.
#
# Note that this script is a quick hack and tightly bound to the current
# groff.texinfo macro code. Hopefully, a new texinfo version makes it
# unnecessary.
