But it does not do so consistently: C-M-b jumps back up to including the
predicate name, but C-M-f from that position only jumps forward up to
the opening parenthesis, and not including the whole construct.

In other words, starting from:

    test(a,b).HERE

pressing C-M-b yields:

    HEREtest(a,b).

but then C-M-f yields:

    testHERE(a,b).

whereas one would expect, for internal consistency:

    test(a,b).HERE

All the best,
Markus
