When I hit the ⌘ + / shortcut to comment the current line of code (I believe this comes from the Source TextMate bundle), the way this bundle is configured the comment gets appended at the very beginning of the line instead of respecting the current level of indentation.

Given the following Sass:

body
  :color white
  :background-color black

Commenting the color style yields the following:

body
//  :color white
  :background-color black

Here's what I would expect:

body
  // :color white
  :background-color black

I just started using Sass, but my take on it from testing is I think Sass treats the current format as if it were a block comment. The background-color style is nested under the comment so it's commented as well.

Here's a link to my commit that has worked well for me so far: lmarburger@fd30c55
