os.spawnv fails when argv is a length 1 tuple.

For example, this will fail:
os.spawnv (os.P_WAIT, '/bin/pwd', ('/bin/pwd'))

Bug exists on Python 2.4.3 on FreeBSD.
Bug exists on Python 2.3.5 on Gentoo Linux.

Longer example:
----

$ cat test.py
import os

path = '/bin/pwd'

print

print 'calling os.spawnv with length 1 tuple...'
print 'exit code:', os.spawnv ( os.P_WAIT, path, ( path ) )

print

print 'calling os.spawnv with length 1 list...'
print 'exit code:', os.spawnv ( os.P_WAIT, path, [ path ] )

print
----

----

$ python test.py

calling os.spawnv with length 1 tuple...
exit code: 127

calling os.spawnv with length 1 list...
/home/private
exit code: 0

My apologies. I'm new to python and had not realize that

( x )

is not a tuple, while

( x, )

is a tuple.
