Sigh! I should have known better than to use a colloquial English expression
in an international forum :(

That is not a big problem. The trick is to work with three sets of sources:

1. The last Wirth version that you based your version on. 
2. The latest Wirth version. 
3. Your own version. 

You can then use the difference tool to compare 1 and 2 and apply the
results to 3. 

If you are not already using a 'pretty-printing' code formatting tool I
recommend that you start doing so.
