[rdiff-backup-users] Long filename errors

[tkeene]

I am trying to backup a Linux system (ext3) to a Windows system running Cygwin 
and the latest version of rdiff-backup.

How can I prevent long filename errors like this one:

Ideally I would like to be able to back up these files, but at the very least I 
would like rdiff-backup to skip such files and move on. As it is, the whole 
thing comes crashing down.
