Adding a comment only on the originating issue when linking issues
It might just be me, but I get really cobnfused when I see comments that are created from when people create links. It seems that they appear in both the issue the link is being created from and the target issue. This means that comments that makes sense on the original issue sometimes can be very confusing in the target issue.
eg. JRA 8326 and JRA-4619
We should be able to at least choose to not add the comment for the target issue. I would be tempted to turn it off really
Probably a good idea to add a check box, whihc when set will add a comment to both issues. I agree that the checkbox should be unset by default.
