comment Make cd automatically ls
[ -z "$PS1" ] checks if the $PS (interactive prompt variable) is "zero length" (-z). If it is zero length, this means it has not been set, so Bash must not be running in interactive mode. The && return part exits from sourcing .bashrc at this point, under these conditions.

I would file a bug report in its issue tracker: they put out a new version every week, and are quick to respond in general, I've found.

comment Select between given characters in vim
I don't know anything other than what it says at :help text-objects. I don't use that plugin, and would never even consider it if it interfered with such basic vim functionality.
