	Indeed it may be worth to see a difference in the output for
  Clifford units with different representation labels. I include a
  patch which give this in the way which is shown by such an example:

#include <ginac/ginac.h>
using namespace std;
using namespace GiNaC;

int main() {
	try {
		varidx mu(symbol("nu", "\\nu"), 3);
		ex     basis1 = clifford_unit(mu, diag_matrix(lst(1, 1, 1)),0),
		     basis2 = clifford_unit(mu, diag_matrix(lst(1, 1, 1)),1);
		
		ex e00 = basis1.subs(mu == 0),
			e10 = basis2.subs(mu == 0);

		cout << e00 << endl; 
		// <-- e~0
		cout << e10 << endl; 
		// <-- e[1]~0

	} catch  (exception &p) {
			cerr << "Got problem: " <<  p.what() << endl;
	}
}

	Best wishes,
	Vladimir
