Editing does not auto indent code

## Issue Description ##
When entering C# code, if the line is against the left margin, hitting the ";" at the end of the line does not auto-indent the line. It used to prior to some update of the C# extension.

If the code line is even one space away from the left margin, hitting ";" WILL indent the line properly.

## Steps to Reproduce ##
Type in some code, make sure it started at the left margin. Type a ";" to end the line.

## Expected Behavior ##
Code automatically formats and indents to line up with rest of the code.

## Actual Behavior ##
DOES NOT indent - code stays at left margin. UNLESS code is at least ONE column over - then code will indent.
