have_thmss: handle multiple lists of arguments;
paulson [Thu, 29 Jun 2000 16:50:52 +0200] rev 9191
now freezes Vars in order to prevent errors in cases like these:
Goal "Suc (x + i + j) + ?q ?ii ?jj + k + x = xxx";
Goal "Suc (x + i + j) = x + f(?q i j) + k";
Goal "Suc (x + i + j) = x + ?q i j + k";
Goal "Suc (?q ?ii ?jj + i + j) + ?rq ?ii ?jj + k + ?q ?ii ?jj = xxx";

tidied proofs using default rule equalityCE
paulson [Thu, 29 Jun 2000 12:17:18 +0200] rev 9189
the default equalityCE simplifies proofs
paulson [Thu, 29 Jun 2000 12:16:43 +0200] rev 9188
tidied
paulson [Thu, 29 Jun 2000 12:15:08 +0200] rev 9187
fixed proof to cope with the default of equalityCE instead of equalityE
paulson [Thu, 29 Jun 2000 12:14:45 +0200] rev 9186
now uses equalityCE, which usually is more efficent than equalityE
