Zoltan Somogyi 46d1cfb3b7 Diagnose bad partial pred/func application. 
compiler/typecheck_error_undef.m:
    When reporting an undefined name/arity pair, if the name happens
    to be name of some functions and/or predicates which all have
    different arities, add a sentence to the diagnostic to report this fact.
    (Normally this happens only when the erroneous code provides
    *too many* arguments, because if it does not, then the typechecker
    would know that the code can be read as constructing a closure, and
    would instead report errors for the arguments that have the wrong type.)

    Don't color a closing parenthesis whose open parenthesis
    is not colored.

    Fix an old bug that we have no test case for: add the missing
    initial part of the diagnostic for bugs that report undefined
    *non*-user-defined function symbols. There shouldn't be any such
    errors, but the types permit it ...

tests/invalid/wrong_arity_function.{m,err_exp}:
    Extend this test case to test diagnostic extension described above.

tests/invalid/coerce_syntax.err_exp:
    Expect the color change.
