#2187 Inaccurate limit evaluation

[greenbreen]

This bug is similar to 3276461, but I don't no how to add a comment to that bug, so I'm opening this to add my information. I'm using wxMaxima 0.8.4 running on Ubuntu 10.04. When I evaluate
limit(sin(x)/(x-a),x,0);
maxima returns 0. This may be true for non-zero a, but in the case when a=0 the limit should evaluate to 1.
