- made default setting more compatible with XOTcl 1 * set variables to defaults only when not set already * flag init_called already before init is called, not afterwards (a call to "configure" within init does not clear the already set instance variables)
- Altered Nsf_NextHashEntry() to re-init hSrchPtr when the number of expected entries differs from the number of real entries. This fixes a bug that Michael Aram detected, that happens when multiple hash buckets exist, but on deletion of an hash entries triggers some other deleted from the same hash table. - extended regression test.
