Hi,

Justin reported to me a bug he found while using Excorporate.

In Justin's setup, Excorporate retrieves meeting details from a server
then writes them to a Diary file.  Org agenda reads from that Diary
file.

In the failing case, the meeting details happened to contain lines whose
middles matched diary-time-regexp, e.g. any URL containing 0-9 and then
'h'.  Those non-entry lines were displayed as Diary: entries in the Org
agenda, when they shouldn't have been.

Justin confirmed the attached patch fixes the problem for him.  Can an
Org mode maintainer review it?

Thanks,
Thomas
