CMUCL was computing the values of asin, acos, and atanh on the branch

cuts on the real line incorrectly.  This shows up when calling these
functions with real-valued args, not complex.  The problem was the
computed values were not continuous with the quadrants specified by
ANSI CL.

Issue noted by Bruno Haible, cmucl-imp, 2004-10-11.
