I am afraid that the filter does not work as expected. Some weeks
ago I posted a filter question for version 7.15 into this forum
and nobody could help.
I suspect that the pattern matcher gets confused if there is more
than one quantifier or more than one alternative like
(this|that|other). (Can anyone confirm this?)

Yes, it should.
By the way, `.' perhaps matches carriage returns also, as the
on-line help (version 7.15) on `\s' notes that carriage returns
are white space and in my opinion "any character" should be a
superset of "white space".
