indent(1): Don't ignore newlines after comments that follow braces.

indent.c has a special loop that stores tokens from between an if () and
the next statement into a buffer. The loop ignored all newlines, but that
resulted in not calling dump_line() when it was needed to produce the
final line of the buffered up comment.
