I see in ``lread.c'' that the initialization of `Qt'
and `Qnil' are different:
Qnil = Fmake_symbol (make_pure_string ("nil", 3, 3, 0));
Qt = intern ("t");
`intern' calls `Fintern', which uses `NILP'. This
seems to be the reason why they are initialized
differently. And the string "nil" is in pure storage,
while "t" is not.
Is this correct? Thanks.
