Weekly interval > 1 generates wrong dates

Hello,

Date is a great module on which we rely heavily.

When adding a new content with a date field, selecting repeat option and specifying a weekly recurrence with interval > 1, and selecting the start date which is the first week day selected in the repeat-on days, the wrong dates are selected.

Here is a specific example.

Select Monday 2014-04-28 as the start date, repeat Monday to Friday on every second week. The generated dates will be Monday the 2014-04-28, but instead of filling the rest of days in this week, i.e. Tuesday the 2014-04-29, Wednesday the 2014-04-30 etc., the first week is skipped and the next days are Monday 2014-05-05 followed by Tuesday to Friday of the week after.

This selection of wrong week does not happen if the start date is not the first of the repeat-on days, e.g. in the example above, if the start date is Tuesday 2014-04-29, the rest of the days in this week will be selected as should.

Attached is a fix we use in our code for this. Its a one line.

Feedback appreciated.
