referencing tickets in descending order in commit messages creates duplicate comment numbers

[Richard Rogers <rprogers@…>]

How to reproduce:

1) have 2 tickets with numbers X and Y, where X < Y, Y having more comments than X 2) do a commit with message "refs #Y and #X"

Ticket X gets a new correctly numbered comment, but Y gets a comment with the same number that was added to X creating a duplicate comment number in ticket Y. "refs #X and #Y" seems to work correctly for both tickets.

This doesn't seem to occur with 0.12.4 or 1.0, but it's unclear if the underlying issue has actually been fixed.

We had some issues with comment numbering in early 0.12.x releases, which seem to have been fixed since (although I'm not sure which changeset actually fixed it, but we never saw the symptom again). I would advise upgrading to 0.12.4.
