Day View not displaying reservations of different units with same start time (with apparant fix)

The issue is with agreservations-7.x-2.x-dev, date-7.x-2.x-dev, calendar-7.x-3.x-dev as stated, but this behavior was need in earlier 7.x versions.

The problem is in the "Day View" of agres_views where multiple units have reservations that begin at the same time on the same day. When this occurs, only one of the relevant reservations is shown.

The reason is in agres_view/theme.inc, in template_preprocess_agres_views_day (about line 500), the code iterates over each unit, and then nested, each event. However, when there are multiple reservations at the same start time, they are part of the same event array (with increasing numeric indices). The code does not allow for that, and hardcodes $event[0]->date_start, etc. It does not take into account that there may be $event[n>0] as part of that structure.

As far as I can tell, this is easily fixed by nesting one more loop to iterate over all the "subevents" that may be part if the event array.

Diff is attached.

If there is some Drupal trick that makes this unnecessary, I would appreciate that info.
