• user1 has project associated with HEAD revision of some cvs module
• user2 has a project associated with some branch of the same cvs module
• user1 adds the new file to branch:
  ----> corr. change appears in Incoming view of user2's project, in HEAD branch
• user1 changes the above file, commits:
  ----> corr. change also appears in Incoming view of user2's project, in HEAD branch
• user1 changes the file that exists in branch also, not only in HEAD:
  ---> this change doesn't appear in user2's project.

Thus, oly the changes in HEAD that are made to files not present in branch, appear in Incoming view of projects associated with branches.
I think this behavior is inconsistent: either all changes should appear in Incomng view in HEAD group, or no changes made in HEAD should be visible.
The 1st aproach is preferrable: all the changes made in branch appear in Incoming view of project associated with HEAD (in the corr. group)
