 3# Fix a problem with HTML output produced by makeinfo 4.8.
 4#
 5# groff.texinfo uses (after macro expansion) something like
 6#
 7#   @deffn ...
 8#   @XXindex ...
 9#   @deffnx ...
10#
11# which has worked with earlier versions (using an undocumented feature
12# of the implementation of @deffn and @deffnx).  Version 4.8 has new
13# code for generating HTML, and the above construction produces wrong
14# HTML output: It starts a new <blockquote> without closing it properly.
15# The very problem is that, according to the documentation, the @deffnx
16# must immediately follow the @deffn line, making it impossible to add
17# entries into user-defined indices if supplied with macro wrappers around
18# @deffn and @deffnx.
19#
20# Note that this script is a quick hack and tightly bound to the current
21# groff.texinfo macro code.  Hopefully, a new texinfo version makes it
22# unnecessary.
