This way the user can keep their preferred pushd syntax while enabling
us to use a standard syntax in our defined functions.
To explain further, without a clear value on the PUSHD_MINUS option, we
could be changing the +1/-0 values all we want, that some user would
find that it didn't work for him.
We have two options, then:
- Setting a particular value, which was my first approach.
- Using `emulate -L zsh` to ensure all options defined in the function's
body won't be passed along to the main zsh instance.
For more info see:

This change follows this proposed behaviour:
Ctrl+Shift+Left: move to last visited directory
Ctrl+Shift+Right: move to next visited directory
an alternative behaviour would be:
Ctrl+Shift+Left: move directory to the left in `dirs` output
Ctrl+Shift+Right: move directory to the right in `dirs` output
It also introduces `setopt nopushdminus` as a way to standardise
pushd syntax. It's value wasn't clear before, which has been the
cause of so many pull requests regarding this plugin not working
in some environments.
