[PATCH v2] org-clock: Fix clock report sometimes ignoring hours before :wstart

[Georgiy Tugai <georgiy.tugai@gmail.com>]

[-- Attachment #1: Type: text/x-diff, Size: 5694 bytes --]

* lisp/org-clock (org-clocktable-steps): Fix weekly-step clock report
  ignoring hours between start of period and start of week, when start
  of period is on a day of week numerically less than start of week.

  Clock report now always inserts a "week" starting at the start of
  the period, if necessary; all following weeks start on the start of
  the week as expected.
