When adding watchers to an issue, you should have the possibility to notify the watchers that they have been added to the issue
Sometimes it happens that I want to take 2 actions on an existing issue: Add a watcher + add a note to the issue (or change some other issue-property)
I would like the new watcher to get notified for the changes I make on the issue.
Now, if I forgot to add the watcher, before I make the issue change, then (of course) the watcher does not get a mail.
It would be nice if, when adding watchers, you could decide to send them the issue-information by mail. (so that they know that they are now involved in this issue)
