The pgindent issue isn't at all surprising. If we wanted to fix it the
way would be to get the perl script to rewrite it with something indent
would accept (e.g. move the block outside the parentheses) and then undo
that after the indent had run.
But the block inside parentheses feels kinda funny, doesn't it?
