    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 is a regression test for Mantis bug #109. Its code was derived
% from the function bits/3 in library/bitmap.m.
%
% In high-level C nogc grades, e.g. hlc, hl, hlc_nest, or hl_nest, this
% program used to cause the compiler to abort with:
%
% Software Error: ml_disj_gen.m: Unexpected: ml_gen_disj: single disjunct
%
% The problem was a bug in add_heap_ops.m, fixed 14 Sep 2010.
