So don't use 'C' just use 'M' at the
start and 'L' everywhere else
(actually you don't even need the 'L's since "M
x0,y0 x1,y1 x2,y2 ..."
is the same as "M x0,y0 L x1,y1 L x2,y2 ...").

If you really wanted to you could go
back after they are done
drawing and 'smooth' the curve, but that get's into
'interpolation'
and there is generally no one good answer here. You
could also
potentially use 'Q' which uses the tangent at the
previous point
to generate the control point for a 'C'. But
really most people
just use L.
