How hard would it be for you to separate styling changes from content
changes into two different commits?  That is, it would make your patch a
little easier to review if the first stage were fixing indentation
issues in existing code, with no semantic changes, and the second change
is limited to semantic changes only, instead of the current mix of two
types of changes in one patch.

For example, this was an indentation-only change.

This is not an indentation change, but it is fixing a pre-existing area
of the code, so it would still fit better as a separate cleanup patch,
apart from the real meat.

Here's the first real meat I found in the patch (70 lines in!), but it
still has an issue - you are only stripping one, instead of all, leading
zeroes.  I still think that doing the conversion to int, then the +1
operation, in C, will be much better than trying to do it in shell with
$(()).

My quick glance at spot checks in the rest of the file did see that you
are making progress; you did incorporate what looks like quite a few of
my comments.  However, I did not complete my review this time around
because of the mix of multiple changes in one patch.

On the other hand, I agree that this still seems like something worth
getting in 0.8.2 if we can clean it up fast enough.  Do you need any
help separating the patch into separate stages?
