Quasi-quotes "raw" string

[kamahen]

There are various escapes, both in the pattern and the replacement, that use backslash. These need to be doubled with SWI-Prolog, which makes things even more unreadable.

Enhancement suggestion:use quasi quotations, e.g. {|re||a\b|}. Another possibility is to extend Prolog's syntax, allowing for e.g., R"a\b". As a variable cannot be an operator, nor can a string, this is always illegal syntax in ISO Prolog.
