nameless branch with cvs

[Alexandre]

Hi,
   due to an error a branch containing many version of a file has been
moved to one of its file therefore creating what look like a nameless
branch..  Is there a way to "move back" the branch ( name ).


Was 

Main Tr
   |
  1.1
   |
  1.2----------/ BR_MYBRANCH \
   |                  |
  1.3               1.2.1
  ...                 |
                    1.2.2
                      |
                    1.2.3

And now is
Main Tr
   |
  1.1
   |
  1.2-----------------+
   |                  |
  1.3               1.2.1
  ...                 |
                    1.2.2--------/ BR_MYBRANCH \
                      |
                    1.2.3


Hope this is clear...

Thanks
