didn't know where to put the tab stops.  Another problem
was that some of the code assumed that string byte
offsets were the same as column offsets, which is only
true if there are no tabs.

In the process of fixing this, I cleaned up the arguments
to Fold and ExpandTabs and renamed them Break and
_ExpandTabs so that I could be sure that I found all the
call sites.  I also wanted to verify that ExpandTabs was
