### Description

The resp. Pynac-0.7.17 enhancements should be doctested here:

sage: exp(asinh(2)) sqrt(5) + 2 sage: exp(2*asinh(2)) (sqrt(5) + 2)^2 sage: exp(1/2*acosh(3)) sqrt(2*sqrt(2) + 3) sage: exp(atanh(1/2)) sqrt(3) sage: exp(atanh(-2, hold=True)) # known bug sqrt(1/3) sage: exp(acoth(31)) 4*sqrt(1/15) sage: exp(asech(1/3)) 2*sqrt(2) + 3 sage: exp(acsch(13)) 1/13*sqrt(170) + 1/13

**Note:**See TracTickets for help on using tickets.

This works, except for the marked case above. Reasons?
