This patch fixes the undefined (according to C) and erroneous (under

Digital Uni x with both DEC cc and gcc) behaviour of modifying an
lvalue on the left side an d then using it on the right side of an
assignment. Since this code modifies the
 dbname parameter, it was changing, for example, "dbname=template1"
 into "dbname =emplate1".
