File post-moving and post-renaming feature

[oderon]

I work on many computers but on same files. I keep those files on pendrive for 
easy access and want to have them versioned.
Since space on pendrive is very limited and pendrive itself has different drive 
names on different computers it is not possible for me to keep branch on 
pendrive.
My main branch is on my home computer and i usually copy the files from 
pendrive to branch and commit changes. The problem is with files that have been 
moved or renamed on pendrive without using bazaar commands.

Is there a fast way of telling bazaar which files have been moved and renamed 
or do i have to move/rename them back and forth all the time? If there isn't a 
way i request it :)
