That's an entirely different issue, not directly related to '[...]' in
the lens language. IIRC, one of the reasons to make the smb lens work
the way it does is because Samba section names can contain characters
that make the tree a little harder to work with, particularly because
section names can contain spaces.

There's nothing hardwired in Augeas that requires that, but as you
noted, it also doesn't change what you can express.
