For those who are interested:

    https://unix.stackexchange.com/questions/421904/regression-with-unary-plus
    (Regression with unary plus, by Steven Penny)

As suggested by Stéphane Chazelas in his response, the change in behaviour is
problably not intentional.

Modifying (i.e. extend it) the '0p_unary_plus CASE' in interpret.h, restores
the previous behaviour.
