Zoltan Somogyi 33eb3028f5 Clean up the tests in half the test directories.

    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 debugger tests,
    specify the new line numbers in .inp files and expect them in .exp files.

% This is a regression test for Mantis bug 94. Versions of the compiler before
% 22 Sep 2009 used to generate a spurious mode error for init_message,
% because the term being returned, being in a from_ground_term_construct scope,
% was inferred to be ground, not unique.
