PR Summary
Occasionally TabExpansion2 may return null. This could be due to a custom implementation of TabExpansion2 or an underlying issue with the FileSystemProvider or LocationGlobber.
When this happens the value of commandCompletion is not assigned and remains null. This causes a NullReferenceException to be thrown when commandCompletion.ReplacementLength is accessed in the subsequent call to LogTrace.
