Could people refrain from "X should do Y" when they have no idea how
X currently works?

SMIE's indentation works by parsing backward, so that it stops parsing
as soon as it found the info needed to determine the indentation to use.

It almost always stops long before reaching the nearest "open paren in
column 0".
