Applied patch from Richard McRoberts: A bug that most users probably wouldn't 

encounter occurs in an ac analysis using a linear sweep with only one point.
A rather pathological case.) The original code in acan.c uses a frequency
ncrement of "HUGE" (infinity) which causes a crash when stepping to the second
point. Fixed by making the increment zero, which is tested for in the sweep,
ausing it to terminate correctly after the first point.
