commit f5f7f366fe76b58ac7ab125ea9007f91cd1a33a3
Author: Thiago Jung Bauermann <thiago.bauermann@linaro.org>

    GDB: testsuite: base: Don't return value from top-level (manual)
    
    This patch manually changes "return -1" and "return 0" statements that
    weren't caught by the sed command.
    
    These return statements fall into one of these criteria:
    
    - misaligned line, which is then fixed by this patch;
    - return at top level but inside a block such as save_vars,
      with_test_prefix, foreach, gdb_test_multiple.
    
    Some weren't changed because they didn't meet the criteria above, or
    weren't trivial to check.
    
    There was also one return statement with an unnecessary semi-colon at
    the end, which was removed.
