[Python-Dev] Update PEP 394: Distributions can choose what does python command mean

Hello. Based on discussions in [1], Petr Viktorin and me have drafted a new update [2] to the PEP 394 (The "python" Command on Unix-Like Systems). The update gives distributors the opportunity to decide where does the "python" command lead to, whether it is present etc. Please, see the PR [2] for the suggested changes.
