#13 add unique "next line" indicator to long value export

[Jan "J.J." Kischel]

Currently, long value lines have a simple newline "somewhere" (in .txt diff), and it seems to be impossible to automatically figure out if the next line is the rest of the current value or the next value.

It would be great to have a unique "next line" indicator (like backslash + CRLF + spaces + space in *reg files or like underscore + space + crlf in VB.NET) that shows that the next line will also belong to the content of the current.

You would have two benefits:
- It would look great and tidied up when opening the .txt in a text editor.
- Automatic processing of the .txt file later would be easy-peasy because you just would have to replace it with nothing. :-)
