    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.

% The unification of the argument with vertex(I, V)
% contains two subunifications, one of which instantiates the argument.
%
% This is a regression test. Earlier versions of the code generator used to
% generate LLDS code that referred to vars. Such LLDS code cannot even be
% converted into C source.
