There may be some other cases not found ... seems braces would play a factor (i.e., match on 'if () statement= '- like cases. I scanned the patch and seemed to see the cases that were being handled.

Tested with LINT and GENERIC... not much testing though. --=20 You are receiving this mail because: You are the assignee for the bug.=
