[docs] [issue7642] Minor improvement to os.system doc

[Georg Brandl]

Georg Brandl <georg at python.org> added the comment:

Unfortunately, the rewrap makes it much more complicated to see what  the patch changes (i.e. the whole second part of the hunk only adds Windows versions).  Please leave that to the committer in the future.

Otherwise, committed in r85450; I also removed mention of the unsupported Win9x family.

----------
resolution:  -> fixed
status: open -> closed
