* src/imach.c: 'Not a number' more clear if Hessian not invertable

When the Likelihood can't be maximised in all directions, the Hessian
can't be estimated correctly and can be inverted, or, if it is
inverted, some computed variances are 'negative' and their square
roots produce, in C language, what is called a 'nan' which means 'Not a number'.
A new sentence is printed when the Wald statistics are produced.
