Yes, I have read this comment. I though that this is a lexer
indicator, that's why I set to 1, right after the _ERROR. Have I got
it wrong?

I haven't tried that yet. I understand I would need to increase some
API level to see that. I am using Geany 0.20 that is distributed with
current Fedora.

I don't think it is good idea for me to touch it. I have very little
understanding how Geany, Scintilla and Gtk work, and truth be told, I
don't do C coding in Geany. I need Python tools and this is what I
would like to focus on :-)
