Bug 9649

See http://catb.org/~esr/doclifter/problems.html for details on how and
why these patches were generated.  Feel free to email me with any questions.
Note: These patches do not change the mod date of any manual page.  You
may wish to do that by hand.

Problems with Xaw.3x:

1. Ambiguous or invalid backslash.  This doesn't cause groff a problem.
but it confuses doclifter and may confuse older troff implementations.

2. Use of low-level troff hackery to set special indents or breaks can't
be translated. The page will have rendering faults in HTML, and
probably also under third-party man page browsers such as Xman,
Rosetta, and the KDE help browser.  This patch eliminates .br, .ta, .ti
and .in in favor of requests like .nf/.fi, and .RS/.RE that have
structural translations.
