    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.

% Description of bug:
% The liveness of polymorphic type variables for accurate gc
% wasn't being computed correctly in the case of if-then-else.
%
% Symptom(s) of bug:
% A sanity check in liveness.m is failed.
%
% Software error: branches of if-then-else disagree on liveness
% Then: HeadVar__3 TypeInfo_for_Y
% Else: HeadVar__3 TypeInfo_for_X TypeInfo_for_Y
