compiler/det_report.m:
Generate an error message if a require_complete_switch [X] scope
is wrapped around a goal that is not a switch on X.
doc/reference_manual.texi:
Update the reference manual to document this change. Also fix an
old documentation problem: require_complete_switch scopes do NOT
require covering all the function symbols in the type of the
switch-on variable if the switched-on variable's inst says that
it cannot be bound to some of them.
compiler/hlds_goal.m:
Update the comment on the require_complete_switch scope
in the same way.
NEWS:
Announce the change.

tests/invalid/Mmakefile:
For the bug257.m test case, which has a require_complete_switch [X] scope
around a goal that is not a switch on X, expect the error message
we now generate, not the old warning.
Since the compilation of bug257.m now fails, move it from warnings
to invalid.
tests/valid/Mmakefile:
Disable the bug257b.m test case, which also had a
require_complete_switch [X] scope around a goal that was not a switch on X.
tests/valid/bug257b.m:
Document that this test case is now disabled, and why.
