    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 problem was that the name mangling scheme used for the names of method

% have been reporting the instance tc(V) as an error anyway, but it wasn't
% doing that check until *after* it had attempted to add the method wrapper.
