Well, one thing I've noticed is that when a function prototype wraps
around to the next line, you often change the number of spaces in the
hanging indent.  I would do them the way that you want them if I could
figure out what the rule was, but I can't.  When I asked before, you
said that you let emacs do what it wants, but with apologies for using
the Other Editor, that doesn't actually help me very much.

I am also a bit confused about the rule for indenting the variables in
variable declarations.  I get that the *, if any, is suppose to hang
to the left of the name, so that the first character of each variable
name lines up - and in particular, line up on a tab stop.  But it's
not obvious to me how to choose which tab stop to line everything up
on.
