Spaces around the '=' sign have to be removed. This is provided
by inp_remove_excess_ws().
If the 'altermod' argument is 'altermod m1 vth0=0.7', 'm1' has to be kept as the
element in wl2 before splitting inserts the three new elements.
If 'expression' is a vector (e.g. [ 1.0 1.2 1.4 ] ), its elements
in wl2 have to follow the splitting. wl_splice() will take care of this.
