[issue355] smart upgrade crashes on serial or xen terminal

[Peter Warasin at Labix Tracker]

New submission from Peter Warasin <peter at endian.com>:

if you try to smart upgrade through a serial console or a xen console smart
crashes with this traceback:

...
  File "/usr/lib/python2.4/site-packages/smart/backends/rpm/pm.py", line 309, in
__call__
    self.prog.show()
  File "/usr/lib/python2.4/site-packages/smart/progress.py", line 110, in show
    self.expose(topic, percent, *info)
  File "/usr/lib/python2.4/site-packages/smart/interfaces/text/progress.py",
line 108, in expose
    out.write(self._topicmaskn % (n, topic))
ValueError: unsupported format character '-' (0x2d) at index 9

This happens because getScreenWith() returns a window size of 0 for those
terminal emulations.
The attached patch returns a default value of 80 when the window size is 0.
