I am going to guess that you wanted a tab instead of a space.

So, I think I have implemented all of the new changes.

One more thing - my intent is that when they are committed, that 
catrig*.c should be split into to two files.  One contains casin(h) and 
cacos(h).  The other contains catan(h).  And then some of those headings 
surrounded by boxes can be removed.

But that is up to you guys.
