- Add --filter-claim and --filter-label switches; parse as symbols, and
turn into (global?) terms, add to switches termlists. Later check them
using two new term functions:
const char *termSymbolString(Term t);
int termSymbolEqual(Term t1, Term t2);
Iteration through the termlist should be done by hand.
- --check is slightly f***ed up because there is no good semantics for
the --disable intruder check. As a result, it is now too strict can
cause correct protocols to fail. Fix.
