UnknownFormatError should tell the URL to that bzrdir

[Alexander Belchenko]

I have some disk failure on the server, as result format file of .bzr was truncated to 0 bytes. Trac unable to provide timeline, and `bzr branches` command is also failed with the same error:

bzr: ERROR: Unknown bzrdir format: ''

Unfortunately there is not much info where is actually broken bzrdir located.

Please, add the URL of the bzrdir to the error message, so it will be much easier to find a broken branch.

Please provide a traceback so we know where to add the missing URL :)

IIUC, the URL should be passed into error constructor.

But if you want to see a traceback.. It's easy:

bzr init .
echo ""> .bzr/branch-format
bzr -Derror st

C:\Temp\2>bzr -Derror st
bzr: ERROR: bzrlib.errors.UnknownFormatError: Unknown bzrdir format: ''
