The reason for the error were the text preprocessor added to deal with
tabs was created to process entire files, not just lines or words. In
that context it cleaned trailing new lines if any existed but in the new
role that's not only unwanted but erroneous.
### Problem description
After that was fixed the console started to add two empty lines between
each output line. When splitting a string using new lines you need to
not add a new line to the last line created. Even if the text ends in an
end line, the split screen code is set to not discard empty lines.
### Implementation description
The fixes are straightforward.
