* before the range that needs to be folded as this allowed fixing up
* the last line from the previous folding.
* The new approach allows the lexer to decide whether to backtrack
* or to handle this more efficiently.
*
* Lessons I have learned so far are
* - do not start with a base level of 0 to simplify the arithmetic int calculation
* - scintilla recommends to use 0x400 as a base level
* - when the value becomes smaller than the base value, set the base value
* - create an additional margin in which you set the levels of the respective lines,
* so it is easy to see when something breaks.
