Comment(by drkirkby):
Yes, we can get this to pass, but that is just covering up a bug, as the
number should never be printed as {{{.8813735870195429}}} It is a
numerically correct result, but it is not printed the way one would expect
a piece of software to print the number.
Carl Witty is of the opinion this is either a Maxima or ECL bug

I think its better to leave the {{{asinh(1.0)}}} case failing. It will be
a constant reminder we need to get a real solution, not hack the doctest
to get it to pass.
Ultimately, I feel the doctest has discovered a bug, which is what a good
test should do.
