RRULE showing wrong dates depending on WKST

[acmurmeltier69]

Hi
another strange behavior on RRULE in v2.03
The following RRULE is used in the attached file "recurrance_simple1.ics"

DTSTART;VALUE=DATE:20170313
RRULE:FREQ=WEEKLY;UNTIL=20171224T000000Z;INTERVAL=2;BYDAY=MO;WKST=SU

It correctly creates
13-03-2017
27-03-2017
10-04-2017
...
However if I change "WKST" to Monday (file "recurrance_simple2.ics"), i.e

DTSTART;VALUE=DATE:20170313
RRULE:FREQ=WEEKLY;UNTIL=20171224T000000Z;INTERVAL=2;BYDAY=MO;WKST=MO

All dates after the first one are off by one week
13-03-2017
20-03-2017
03-04-2017

Separated the problem with EXDATE spanning multiple lines into a new issue #114.
It seems to be caused by a different, non-related issue.

Thanks! Works on my side.
