This appears to do something more or different to fixing definitions -
if it was fixing I'd expect to see equal numbers of lines added and
removed in blocks identical apart from some numbers but this appears to
be adding some new definitions like these...

...among other things, and this block here:

removes a lot more things than it adds, with different names too.
