Changes between Initial Version and Version 1 of Ticket #10742, comment 8

initial	v1
2	2	> 1. `comment:N` and `comment:N:ticket:M` should display with class `missing comment` when ticket M does exist and the user has permission to view ticket M, but comment N does not exist. For example, compare: comment:1 vs comment:100000 and comment:1:ticket:1 vs comment:10000:ticket:1 - the latter in both comparisons the latter example should display as a missing link.

4		The `comment` class can't be used for TracLinks since it is already used on the ticket page for the `div` that encloses the comment text. I've the class `ticket-comment` instead. I wonder though whether there is any value in adding this class, or whether I should just use the `ticket` class for TracLinks prefixed with `ticket:` or `comment:`.
