Refactored the WPCLI
module to build and escape string command lines differently; the handling of command-line arguments
for the WPCLI
module has been modified to make it a bit more consistent and robust; as a consequence, you might experience
some breakages in string commands that used to work correctly before; should this be the case then either modify
your code ot provide the command in array format (taking care of the correct escaping in your code), or make sure to
pass a correctly structured command string to the WPCLI
module.
