* claim: #9332

* Expressions: hyperbolic functions sinh, cosh, tanh and their inverses (#9332)

`sinh`, `cosh`, `tanh` and `asinh` take a unit-less number and give one,
as `exp` does; `acosh` refuses x < 1 and `atanh` refuses |x| >= 1, worded
as `asin` and `ln` refuse what lies outside their domain. They are in the
expression help (`FUNCTIONS`, the parameter autocomplete), the
hostile-expression fuzz tokens, the parameters and equation-curve guides,
and the checking skill's list of functions. Horn flares (Salmon's hypex
`cosh h + T sinh h`), catenaries and the tractrix can now be written as
they are stated instead of expanded into `exp`.
