    canvas-item: Don't wrap after . immediately followed by numbers
    
    Nautilus allowed line wrapping for filenames after a . or _
    The code made an exception for version numbers, but it
    was too rigid and broke things like Ubuntu's 12.04 version
    numbering. This relaxes the exception so that the line isn't
    wrapped for a . or _ immediately followed by any numbers.
