    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.

% This test case checks the correctness of the code that performs
% the fixpoint loop returning answers to consumers. The fixpoint
% computation has to repeatedly switch from one consumer to the
% other to obtain all answers for p/1.
