I don't recall you mentioning that.

There are no changes in this patch that are purely whitespace changes.
Those were removed prior to patch submission. This is all about code I
am adding or changing. My additions may disrupt their patches, but not
because of the whitespace.

If we are going to run pgindent anyway, what is the point? Seems like we
need a tool to fix patches, not a tool to fix the code.

I've made some changes to the larger files.
