For exp-integral-e, use the series for small z and the incomplete-gamma-tail for near the negative real axis. Otherwise, use the continued fraction. In incomplete-gamma-tail, we were using the continued fraction instead of the incomplete-gamma function for the region just below the negative real axis. We should use the cf except in that region.

The blanks were for testing integration of git and trac to close trac tickets. It's working now.

incomplete-gamma-tail. qd-gamma.lisp: o For integer values, just compute the gamma value directly by multiplication. This works around the problem that the current algorithm is not as accurate as we would like. rt-test.lisp: o Reduce required accuracy in gamma-incomplete-tail.3.d. o Add precision test for gamm incomplete tail near the negative real axis.

o Use the new continued fraction for the incomplete-gamma when the argument z is close enough to the negative real axis.

some random clean ups. o Add *DEBUG-CF-EVAL* to enable debugging prints in LENTZ. o Modify LENTZ to terminate with an error if *MAX-CF-ITERATIONS* is reached. o Modify LENTZ to return the function value, the number of iterations, and the number of times a zero value had to be replaced. o Adjust cf-incomplete-gamma and cf-incomplete-gamma-tail not to signal overflow prematurely when calculating z^a*exp(-z). o Fix doc bug in reference for continued fraction for (original) cf-incomplete-gamma. o Add new version of cf-incomplete-gamma using a different continued fraction. This appears to converge faster and to be more accurate than the original, especially for points near the negative real axis.
