Description

After the fix of the #15850, I guess, editor:toggle-line-comments works incorrectly in tab-indented file on empty indented lines.

Steps to Reproduce

1. Open file with tab-based indentation
2. Go to the empty line
3. Indent
4. Run editor:toggle-line-comments (ctrl-/)

Expected behavior: Line indented by tabs (like the rest of the file) and starts with comment symbol(s).

» » foo
» » #·

Actual behavior: Indentation becomes by spaces.

» » foo
····#·

Reproduces how often: 100%

Thanks for the report, I can reproduce on Atom 1.22.1 with macOS 10.12.6 - with this snippet indented by tabs and Settings > Editor > Tab Type set to hard:

var hi = function() {
    console.log("hi");

    console.log("bye");
}

On 1.22.1:

Previous behavior in 1.21.1:
