FactSpan built both instants by adding a duration to local midnight, so on
the two DST changeover days every span was an hour off. A day is 23 or 25
hours wide there, and the busy gate then read a 14:00 meeting as 13:00 or
15:00. Both readings are time.Date now, and the midnight crossing is AddDate
rather than a 24-hour add.
The iCal parse did not unfold content lines. A server folds a property at 75
octets and a Russian summary is two bytes a letter, so the tail of an
ordinary weekly standup was read as an unknown property and dropped, and the
event was filed under a truncated name. RFC 5545 TEXT escapes are also
reversed now, which RenderICal has always written and the parse never undid.
Two regression tests: a folded and escaped summary, and a span across the
start of DST in Europe/Berlin.

Radicale becomes a write-only render target, not a store. sqlite stays
canonical: every poll mavcaldav reads the pending reminders out of core and
publishes each one as a single-event iCal resource, withdrawing the ones that
have fired or been cancelled. Losing the collection costs nothing — the next
tick rebuilds it, and nothing is ever read back from it.
It structurally cannot write to a calendar maven only reads. The render URL and
credential are their own flags, and -render-url is refused at startup when it
names the collection -url reads; the only paths it addresses carry the
maven-reminder- prefix, so even aimed at the wrong collection it can only touch
resources it created. Rendering is off unless -render-url is given.
The calendar data model now lives in one place, internal/calendar: the Event,
the iCal parse it comes from and the render it goes to, the fact key/value
encoding, and the source constants that say which calendars may be written to.
It was a parse inlined in cmd/mavcaldav and a Sprintf in two files; #126 and
#128 both need to agree with it.
Fixes a latent day-boundary bug moved out of that inline parse: it took the day
number off a local clock reading but built the window boundaries in UTC, so on
a box east of Greenwich part of the evening fell outside "today" and the poller
saw an empty calendar after 20:00 UTC. Today is now the owner's day in the
owner's location, which is what the busy gate and the day plan mean.
