C scope highlight problem with newlines in if statements

[Danielkonge]

Problem

Scope highlighting doesn't have the expected behavior with certain formatting styles.

This is the expected behavior:

I think these are also all okay, but I am not sure about the exact scopes here:

This is wrong:

As shown in the first few pictures, this highlighting can be fixed by changing the formatting a bit, but hopefully the code should still work correctly in this case.

Steps to reproduce

nvim --clean -u min-init.lua keeps giving errors when I run it with the minimal config file, so I don't have the minimal config, but I don't think the issue is hard to reproduce.

Make a c file with:

int main(int arg1,
         char **arg2,
         char **arg3
         )
{
  if (arg1 == 4
    && arg2 == arg3) {
    int tmp = 1;
    // comment
  } else {
    int tmp  = 2;
    // comment
  }
}

Move the cursor around different lines and look at the scope highlights.

Expected behavior

In this picture the scope should highlight the second indentation guide to the left of the cursor.

Isn't this just a duplicate of #752

I didn't think it was the same problem because the indent guides looked different, but looking at it again I think that is just because of smart_cap_indent. I think you are right that this is a duplicate, so I will close this issue and make a comment in the other issue instead. I think I might have a way to solve this after current_indent is committed (I would use that the calculation loop and drawing loop are different then).
