It's very cautious, and not very clever. :-(

Problem is, it would have to analyze the string in a lot of detail to
discover for sure that that particular colon was not an item separator
(and so had to be doubled). I suppose it could just guess that "{:}"
wasn't going to be a separator, but how common is this particular case
likely to be? In other words, is it worth my spending time on it instead
of on other things that need doing? My current feeling is that the
answer is "no", I'm afraid.
Thanks for taking time to raise the issue.
