backslash in file names

[Stefan Monnier]

I recently had to convert an Arch repository (formely CVS repository)
where some file names had backslashes in them.  bzr-import burped
on them.  It seems that Bzr does not support such file names, even
though they work just fine in CVS and even in Arch.

I understand that backslashes in file names can be problematic under
w32, but when converting existing repositories we don't have the luxury
to adapt the file names to the constraints imposed by the tool.

Could we change the check in inventory.py so that when it encounters
a backslash it emits a warning rather than signalling an error?
