// position but we do the tracking ourselves to properly deal with virtual space. To
// ensure the end location is correct, we take three extra steps:
// 1. Insert an empty comment ("/**/" or "'") at the current $end$ position (prior
// to formatting), and keep a tracking span for the comment.
// 2. After formatting the new snippet text, find and delete the empty multiline
// comment (via the tracking span) and notify the IVsExpansionSession of the new
// $end$ location. If the line then contains only whitespace (due to the formatter
// putting the empty comment on its own line), then delete the white space and
// remember the indentation depth for that line.
// 3. When the snippet is finally completed (via Return), and PositionCaretForEditing()
// is called, check to see if the end location was on a line containing only white
// space in the previous step. If so, and if that line is still empty, then position
// the caret in virtual space.

// putting the empty comment on its own line), then delete the white space and
// remember the indentation depth for that line.
