Description

The Google style guide http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml#Code_formatting requires indenting by two spaces for nested code, but by 4 spaces when continuing a statement or declaration on the next line. This configuration doesn't seem to be possible.

Research direction
The issue requests implementing separate indentation settings for continuation lines (e.g., 4 spaces) versus nested code (e.g., 2 spaces) as per the Google style guide. To implement this, one would need to modify the TypeScript formatter logic in the language service, likely in files such as src/services/formatting/. There are no linked PRs or recent comments; the issue has been open since 2015. Investigate the current indentation configuration options and add a new property to distinguish between nested and continuation indentation.
