Missing/faulty documentation for date_period::expand

[anonymous]

From http://www.boost.org/doc/libs/1_37_0/doc/html/date_time/gregorian.html

date_period expand(days)

Add duration to both begin and end.

This is the same documentation as for date_period::shift, and it doesn't make any sense for expand.

expand is documented further down like this:

date_period expand(days)


Subtract duration from begin and add duration to end.

date_period dp1(date(2002,Jan,4),
                date(2002,Jan,10));
dp1.expand(days(2));
// 2002-Jan-02/2002-Jan-12

The one I have a problem with is sorted under the "Mutators" header. It could probably have the same documentation.
