Register rbssh in an environment variable.

This is a convenience method for making sure that rbssh is set properly in the environment for different tools. In some cases, we need to specifically place it in the system environment using os.putenv, while in others (Mercurial, Bazaar), we need to place it in os.environ.

Parameters:envvar (unicode or bytes) – The name of the environment variable.
