single_line_if_else_max_width doesn't apply to if-only expressions?

[Sushisource]

If I've got a nasty blob like:

  fn neighbor_count(&self, x: usize, y: usize) -> i32 {
    let mut count = 0;
    if x >= 1 {
      if y >= 1 && self.ca_grid[x - 1][y - 1] {
        count += 1
      }
      if self.ca_grid[x - 1][y] {
        count += 1
      }
      if self.ca_grid[x - 1][y + 1] {
        count += 1
      }
    }
    if y >= 1 && self.ca_grid[x][y - 1] {
      count += 1
    }
    if self.ca_grid[x][y + 1] {
      count += 1
    }
    if y >= 1 && self.ca_grid[x + 1][y - 1] {
      count += 1
    }
    if self.ca_grid[x + 1][y] {
      count += 1
    }
    if self.ca_grid[x + 1][y + 1] {
      count += 1
    }
    count
  }

Ideally those ifs would get flattened if I they fit under single_line_if_else_max_width, but rustfmt seems intent on breaking them up. Am I missing something, or is this expected?

This is intentional. single_line_if_else_max_width only applies to if which appears inside nested expressions. Please see #1783 (comment) for more.

[Sushisource]

Is there a setting that'll get these types of lines to flatten out? I wasn't able to find one.

[topecongiro]

Unfortunately no, there is not.

This is a feature I would find extremely useful and am amazed it does not exist.
This is probably my biggest hate in rustfmt.
Any chance we can get it added as an option?
