General question regarding interrupting bzr operations

[Nicholas Allen]

> Manual recovery is typically needed.
Would it be possible to have a command bzr repair that would check if 
the tree was invalid somehow and perform these steps? Also before a pull 
could you not create a "patch" with the local changes and store it in a 
temporary file so if things really go wrong then you can revert and 
apply the patch again - bzr could keep track of patches it created and 
in the repair could ask the user if they would like to apply the patch 
back to get local changes they had.

It's just an idea - not sure if this makes sense and could be 
implemented though....

Cheers,
