Identing in Vim

[beo wulf <beowulf@...>]

I'm using the default lua.vim, ... and indenting seems to work for
everything (function/end, do/end, ...) except for multiline function
arguments. For example, lua.vim wants to indent

foo(
a,
b,
c);

whereas, I would prefer the identing to be:

foo(
  a,
  b,
  c);

Anyone else have this problem? Basicaly, when there's a function call,
I'd prefer the args to be indented), whereas lua.vim justifies it to
the left with the "f" in function.

Thanks!
