overwrote a branch

[Loic J. Duros]

Hello:

I have basically two branches in my repository: "dev" in which I do all 
the dev work, and "trunk", in which I mostly merge stuff from dev when 
I'm ready to create a new version.

My local dev branch is checked out from the remote one (on savannah). 
Today I wanted to do 'bzr merge ../trunk' to get a commit I made on my 
local trunk, but instead I did 'bzr pull ../trunk', and as a result my 
remote and my local dev branch are just a copy of the trunk. I used to 
have 889 revisions in dev, only 539 in trunk, but now both of them show 
539. How can I get my old branch with the 889 commits? I should mention 
that all the revisions from dev were probably merged to trunk, but it's 
hard to tell since they get aggregated under a new number and commit text.

here is the dev branch: 
http://bzr.savannah.gnu.org/lh/librejs/dev/changes/541
and here is the trunk: http://bzr.savannah.gnu.org/lh/librejs/trunk/changes

Many thanks for your help,

Loic
