    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 tests
    that check compiler error messages, expect the new line numbers.

browser/cterm.m:
browser/tree234_cc.m:
    Import only one module per line.

tests/hard_coded/boyer.m:
    Fix something I missed.

% Check that we handle repeated type class constraints on pred declarations
%
% We check this twice in this module: on the predicate 'p/1', and on the
% class method 'foo/2' which repeats the 'fooable/1' class constraint that
% gets introduced by the compiler because it is a class method.
