    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 compiler used to abort in this code
% when both frame optimization and value numbering were turned on but
% full jump optimization wasn't.
%
% The reason was that frameopt, in keeping the stack frame of det_insert_fcl,
% would generate the instruction sequence "livevals, assign to succip, goto",
% which violated an invariant expected by value numbering, namely that
% the livevals giving info about the variables live at a goto must
% immediately precede the goto. (Fulljump fixes the problem by eliminating
% the goto.)
