bug#68653: Excorporate: generate better org timestamps

[Thomas Fitzsimmons <fitzsim@fitzsim.org>]

Hi Benjamin,

Thank you for the patch.  From my testing, when org-schedule is passed a
start and end date separated by "--", it only includes the start date in
the range.  Therefore, your patch as-is would be a regression because it
would omit the end date.

Unless I am missing something, an Org date range cannot express an end
timestamp on a different day.  I guess that is why I originally used the
<start>--<end> notation, and appended --<end> after the org-schedule
call.

Can you test the attached amended patch (whitespace-only changes
omitted) and confirm it works as you expect for same-day events, while
preserving the existing behaviour of end timestamps of multi-day events?

(A more ambitious plan would be to add support to Org for multi-day
ranges, then have Excorporate use that new format instead, but no users
have complained about --<end> so far, so I am fine continuing with that,
and adding the hour ranges as you suggest.)

Thank you,
Thomas
