About "problem with quotes": maybe [it's part of gettext feature](https://www.gnu.org/software/gettext/manual/html_node/Scheme.html), GIMP Script-Fu extension can use "_" without a space before the string (see ```gettext shorthand```).
So maybe it's not a bug in the canonical sense, but it's a problem for all Scintilla-based editors (I don't like SF.net, I don't have an account and I cannot say anything about the future :confused: ).
