DOH!
You are right!

Yes. That is the part that confuses me. It think it should care about the
the first colon in the COMMENT statement because it separates the statement
from text and don't care about colons after that first one. Or at least
this was the behavior in rrdtool 1.0.x

Yes. If I escape the collons with \ and escape the escape character it works.

Escaping all relevant colons (and escaping the escape character) is not to much work ...

Thanks a lot!
