    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 is a regression test. The propagation solver approach to constraints
% based mode analysis was failing to consider implied modes and therefore
% failing, because the `in' mode of foo implied X wouldn't be produced,
% but the `out' mode of bar implied the call should produce it.
