dissect calls fclose with a possibly NULL pointer

[Peter da Silva]

Dissect has a number of other problems. For example, it never closes any
of its file pointers when returning from 'handle'. This is OK for BSD
based systems with scads of file descriptors, but I can't hack it. I'll
post a more complete fix next time I get on ficc.
