        <pre>Hi,

when running clang-format over a large in-house C source base, I noticed that
it resets the indentation of comments before ifdefs to 0, although an empty
line was placed between comment and #ifdef.
(I understand that it resets the indentation to 0 if the comment is directly
before the ifdef, because then, we can assume that the comment belongs to the
ifdef)

But if there is an empty line in between, I think the comment should instead
follow the indentation from the code before the ifdef or (if unsure),
clang-format should just keep it as it was. (?)

Example:

It changes:

void f(void)
{
 char c;

 /* Comment */

#ifdef FOO
  ...

Into:

void f(void)
{
 char c;

/* Comment */

#ifdef FOO
  ...

I am using clang-format 4.0.0 but I don't think this ever worked (tried many
versions in the past few years).

Thanks,
Clemens</pre>
