Mechanically kill hard sentence breaks.

mdoc(7): Use the new feature of the .In macro.

mdoc(7) police: Use the new .In macro for #include statements.

Remove whitespace at EOL.

mdoc(7) police: normalize .Nd.

mdoc(7) police: fixed broken references.

Introduce .Lb macro to libcalendar manpage.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq

Delete "typedef ... date" (see style(9)).
In the man page Use ".Pp" instead of blank lines, adopt English
and stress that the Julian->Gregorian switch took place at
different dates in different countries.
