Another bit of ISO C conversion...

    I don't see why indentation matters here.  Either way, your grep for
    "define FOO" should still show what you describe.

Sorry I was unclear.

I was making two points:

(1) I like the indented style better since I think it's easier to read.
(2) Since I grep for "define FOO", not "#define FOO", I don't see the
ability to grep for the latter as a major advantage of not indenting.
