[New-bugs-announce] [issue33721] os.path.exists() ought to return False if pathname contains NUL

[pacujo]

New submission from pacujo <marko at pacujo.net>:

os.path.exists() returns True or False for all imaginable string arguments except for one that contains NUL ("\0") (Linux). This behavior is not documented in the library. Moreover, it can easily lead to accidents if  an externally supplied pathname were to contain a NUL because most test suites would not try to cover such a pathname.

I propose os.path.exists() should return False even in this case.
