To refer to trac tickets in commit messages the basic syntax is of the form [command] [ticketreference]. A colon between the command and the ticket reference is allowed. The ticketreference also allows to list multiple ticket numbers separated by spaces and/or comma. The word 'and' is also allowed between ticket numbers.

One can optionally refer to tickets with the following words

ticket, issue, bug
