Some incorrect variable names in l3galley fixed

There are other things up here: the cutout code is not working properly at
all. Investigations ongoing.

Fix calculation of cutouts on right of paragraph

The code for left indents allowed for the case where the existing paragraph
shape was shorter than the new shanpe, but the code on the right did not.
This is now fixed. 

Some unit tests are needed for l3galley: will add to 'to do' list.
