What version of scriv are you using? I didn't get the same results as you:

% scriv collect --version 1.0
Collecting from changelog.d
Reading changelog CHANGELOG.rst
Entry 'Foobar' is not a valid version! If scriv should ignore this heading, add 'scriv-end-here' somewhere before it.

$ scriv --version
scriv, version 1.3.1

Oh, I see. It's a duplicate of #100. Sorry for the noise.
