-  # We do not raise an error if the user doesn't exist. This is due to
-  # an unfortunate problem with the "user exists" check in AgenDAV.
-  # The AgenDAV "shares" table is not tied directly to a username, so
-  # we are forced to use a regexp match to decide what rows to delete
-  # from that table. We do so regardless of whether or not the username
-  # exists in the "prefs" table, because that table stores only non-
-  # default preferences -- not all users' preferences.

-    # The "shares" table contains principal URLs, and the "@" symbol
-    # is usually encoded to "%40". These queries do a regex match on
-    # the username after replacing the "%40" with a "@".
-    #
-    # As a precaution, I haven chosen not to delete based on the
-    # "calendar" field here. Nobody should have a calendar named
-    # "user%40example.com", but it's not impossible -- and we don't
-    # want to delete that calendar when the not-necessarily-related
-    # "user@example.com" account is removed. And the usual appearance
-    # of the user's email address in the "calendar" field happens when
-    # he is also the owner, so the calendar does get deleted in the
-    # normal situation.
