Hm.  Reindenting the active back branches would fix the back-patching
issue, but it would also be a pain in the rear for anybody carrying
out-of-tree patches; which is probably the majority of our packagers.

On the third hand, updating such patches would only be a one-time
chore (as long as we fix pgindent only *once*, not anytime the mood
strikes us), so maybe it wouldn't be impossible.  Especially if we
constrain ourselves to just fixing tabs vs. spaces, so that "patch
--ignore-whitespace" could be used to apply old patches.
