At first, thank you very much for your reply.

Of course, I had found and read that part of the documentation before posting here. But in this documentation (and any other I came across), I couldn't find any hint about if and how to encode special characters, about what sort of regular expressions are allowed (Perl, extended, Sed etc.), or about what RE engine is used internally. This is what I meant by claiming "no documentation".

I really was hoping to do something wrong. I'll try to file a bug and enable others to reproduce by giving a simple example with standard configuration so that I don't need to upload mine.
