Item9898: Trailing space at the end of WebNotify subscriber list causes the subscriber to be missed

In WebNotify, I had a list item with a trailing space:

   * Main.UseraCompany: <space>
   * Main.UserbCompany: SomeTopic

While running a type of mailnotify script, the following code showed that UseraCompany was not being read:

my $wn = Foswiki::Contrib::MailerContrib::WebNotify->new($foswiki, $web, $Foswiki::cfg{NotifyTopicName});
print $wn->stringify(1)

The output was:

   * %USERSWEB%.UserbCompany: SomeTopic

After removing the trailing space, the output was, correctly,

   * %USERSWEB%.UseraCompany: *
   * %USERSWEB%.UserbCompany: SomeTopic

I'd say that's more than low. Raising to Normal. Need to confirm on Foswiki 1.1

Hmmm, something is wrong there, but not what you might think. By leaving empty space after the : you are asking for notification of changes to an empty list of topics i.e. no topics. The error - if there is one - comes about when you "remove the trailing space" as that should not notify *, it should still notify for the empty list i.e. no topics.

Either way I can't reproduce this on the latest code.
