Hi,

Currently, viewvc-install throws a traceback if Enter is pressed when user is 
asked a "overwrite/do not overwrite/view" question (empty response, so temp[0] 
throws RangeError).

This patch makes viewvc-install persist in asking the same question until it 
receives a definitive response.

Regards,
Alexey.
