reformatting misses edited ticket comments

[dnedelchev]

I found that tracopt-stile macros are neither listed by diff command nor updated by reformat command. While other untouched comments in the same message (containing tracopt-stile macros too) are processed as expected.
That can be seen on the screenshot I'm attaching: Comment 2 (concerning Revision 100) was edited manually before reformatting and Comment 3 (concerning Revision 101) was not. Comment 3 is upgraded and Comment 2 is not. Hence the error message is raised when tracopt/CommitTicketReferenceMacro is disabled.
