In the course of debugging a site problem found reserve/renewscript.pl logging 
loads of 'Use of uninitialized value in concatenation' errors. 

In the redirects in the script two variables are used to convey failures but if
no failures are encountered remain undef. Initialize the vars to an empty
string and silence the warnings
