Open brace in regex causes auto-indent error

[wbt]

This Issue is very similar to #646.

Steps to Reproduce

1. In Atom, create a new Javascript file or edit an existing one.
2. Add the following lines of code:

   var matches = line.match(/{/);
   console.log("Javascript line to follow");

3. Select that code, and/or all code in the file.
4. Autoindent.

Expected behavior: These two lines of code are indented to the same level, whatever that may be, as shown above.

Actual behavior: The second line, and all which follow, are indented one extra level.
