Original description

What steps will reproduce the problem?

1. Open the attached file with the IDE
2. Attempt an auto-format

What is the expected output? What do you see instead?

I expect the code to be formatted.

Instead:

First time, the IDE went into a loop and had to be forced-quit.

Second time:

Latest nightly build of the IDE includes a new code formatter, based on astyle, that behaves as expected. Please not that the attached sketch will be badly formatter because of a missing / at line 5
