Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.

% A very basic check of integer arithmetic.
|
|
%
|
|
% Note: this test makes use of Mercury-specific features (specifically
|
|
% the use of "`xor`" rather than "^" for the exclusive or operator,
|
|
% and the use of the reverse modes of xor) so it really belongs in
|
|
% the `tests/hard_coded' directory, rather than the `tests/general'
|
|
% directory... but that distinction is pretty much obsolete now that we
|
|
% don't support compiling things with Prolog.
