But you should expect bugfixes to change implementation details,
which is what this is :-)

If you read the documentation, e.g. at
http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/UsingZope.stx
which was current as of Zope 2.6, it says:

 lines

    A lines property is a sequence of strings.

Nowhere does it say "list".

Probably a good idea anyway :-)
When I am considering a major zope upgrade, I do this.
