You might want to add a completion function so tab completion works.

In command.c inside g_completions[], add a line like:

   { "!",              GE, 1,  .function = complete_against_negation },

Then add a new function to command.c and command.h:

   void complete_against_negation(int argc, char** argv, int position,
                                  GString* output) {
       complete_against_commands(argc - 1, argv + 1, position - 1, output);
   }
