Or say:

test.cpp: In function 'int main()':
test.cpp:6:12: error: wrong number of template arguments (1, should be at least
2)
 foo f;
 ^
test.cpp:2:8: note: provided for 'template struct foo'
 struct foo {};
^

that is, make the second message a note, mention the minimum, fix the location
to point to foo, show the default arguments in the declaration.

I would guess that counting how many are non-default is easier, but someone
will have to provide a patch.
