Your example below works wonderfully. However I have a question, for the
sake of understanding.

I do not understand the above regular expressions. I guess \\` to match
the start of string (one extra backslash is required to escape the 2nd).
But I don't understand the four backslash sequence; I guess it inserts
\\ to the string, but why is that necessary?
