The code for that Format text was something like:
if you see a semi-colon, replace it with semi-colon + line break.
Translated to Pascal, that is exactly one line of code.
It is not a problem to bring it back, but that rule for inserting line breaks is simply wrong.
One should take care of tokens, and put a line break only if the semi-colon is the end of a token.
Biggest problem was that, if you click it 2-3 times, your text will end with a bunch of line breaks one after another.
I will really search for better solution. It should not be far away. I just need to study the code of the highlighter I'm using there - the highlighter does know where the end of tokens are.
