Straighten out the docs for os.system(); the Unix and Windows behaviors
really can't be smushed together. Bugfix candidate.

@ -1514,11 +1514,19 @@ Execute the command (a string) in a subshell. This is implemented by
|
|||
calling the Standard C function \cfunction{system()}, and has the
|
||||
same limitations. Changes to \code{posix.environ}, \code{sys.stdin},
|
||||
etc.\ are not reflected in the environment of the executed command.
|
||||
The return value is the exit status of the process encoded in the
|
||||
format specified for \function{wait()}, except on Windows 95 and 98,
|
||||
where it is always \code{0}. Note that \POSIX{} does not specify the
|
||||
meaning of the return value of the C \cfunction{system()} function,
|
||||
so the return value of the Python function is system-dependent.
|
||||
|
||||
On \UNIX the return value is the exit status of the process encoded in the
|
||||
format specified for \function{wait()}. Note that \POSIX{} does not
|
||||
specify the meaning of the return value of the C \cfunction{system()}
|
||||
function, so the return value of the Python function is system-dependent.
|
||||
|
||||
On Windows the return value is that returned by the system shell after
|
||||
running \var{command}, given by the Windows environment variable
|
||||
\code{COMSPEC}: on \code{command.com} systems (Windows 95, 98 and ME)
|
||||
this is always \code{0}; on \code{cmd.exe} systems (Windows NT, 2000
|
||||
and XP) this is the exit status of the command run; on systems using
|
||||
a non-native shell, consult your shell documentation.

Availability: \UNIX, Windows.
