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.

Use color in typecheck_error_undef.m ...
... and change the coloring done in many other modules.
compiler/typecheck_error_undef.m:
Add color to the diagnostics generated by this module.
In a few cases, improve the wording of the diagnostic.
Make the name of a function and of a function symbol more descriptive.
Convert some predicates from using many clauses to using
an explicit disjunction.
Delete a function that was sort-of a specialize version of a
utility function in error_spec.m.
compiler/hlds_error_util.m:
Change the functions that return descriptions of predicates and procedures,
mostly for use in diagnostics, to allow the parts of those descriptions
specific to an individual predicate or procedure to be colored *without*
coloring the generic parts (such as the word "predicate" or "function").
Add simpler versions of the affected functions for use cases that
do not need any coloring.

Handle color changes next to prefixes/suffixes.
compiler/write_error_spec.m:
Redesign the code we use to decide what text goes onto each line.
The new design rests on these two new principles:
- Representing the current word separately from the words before it
on the line. This allows us to merge together an arbitrary number
of prefixes, a plain word, and an arbitrary number of suffixes
without the two additional passes that the old algorithm used
to accomplish the same goal.
- Representing the spaces between words *explicitly*. Together with
the previous principle, this allows us to do case analyses of the
possible configurations of text, spaces and color changes with
significantly simpler code than was possible with the previous design.
The new code is longer, but
- it is easier to see both that it does the right thing in each
of these situations, including interactions between prefixes and
suffixes on the one hand and color changes on the other, and
- it is easier to check that all possible combinations of the
relevant circumstances have code to handle them.
compiler/typecheck_error_undef.m:
Use the new capability by using color in arity mismatch reports,
which have the form of "(4, should be 2, 3 or 5)", where the numbers,
which are surrounded by two parentheses which are respectively
a prefix and a suffix, are colored.
compiler/error_spec.m:
Exclude from the list of pieces to be colored not just any final
subsequence of newline pieces, but any initial subsequence of newlines
as well. This avoids the output having lines which end in two consecutive
color changes with nothing between them: the first of which switches
to a color, and the second of which resets the current color to neutral.
library/cord.m:
library/list.m:
library/one_or_more.m:
library/ra_list.m:
Add a predicate named is_non_empty, which does what its name says,
to each of these modules. In cord.m, this is new functionality,
which is now used by write_error_spec.m. In the other modules,
this new predicate is a synonym for the existing predicate
is_not_empty. These modules were in a minority; all other modules
that had a predicate to test for nonemptyness named it is_noN_empty,
not is_noT_empty.
NEWS.md:
Announce the new is_non_empty predicates.

of write_error_spec.m before this diff would have put around them.

Improve error messages for wrong arity function calls.
compiler/typecheck_errors.m:
When we find a reference to an unknown function symbol/arity pair
but the function symbol itself has definitions with other arities,
we want to print those arities to help programmers diagnose the problem.
When doing this, we used to take into account the arities only of the
data constructor function symbols of the same name; we now also take
into account the arities of the actual functions of the same name.
compiler/hlds_data.m:
Simplify the code for returning the list of the relevant arities
by not filtering out the actual (wrong) arity; this is now done
by the caller in typecheck.m for *both* sources of arities.
tests/invalid/wrong_arity_function.{m,err_exp}:
A test case for this fix.
tests/invalid/Mmakefile:
Enable the new test case.
