subrepo: use code from 71ea5b2b9517 only if Python needs it (issue2795)

With Python >= 2.6 the original code already works correct, therefore the
fix for issue2556 on Python <= 2.5 broke relative subrepositories with
newer versions of Python.

from hgext import color

# ensure errors aren't buffered
testui = color.colorui()
testui.pushbuffer()
testui.write('buffered\n')
testui.warn('warning\n')
testui.write_err('error\n')
print repr(testui.popbuffer())
