Notes:
    Changes in v3:
        - Removed a few unnecessary invocations of x_to_tab()
        - As pointed out by Eric Sunshine, [3] it's better not to introduce
          new random helper functions, so x_to_tab() was replaced by a direct
          invocation of tr(1), in one case that requires use of literal 'Q'
          characters, and by invocations of q_to_tab(), in the remaining cases
          that actually allow use of 'Q' characters to represent HTs
        - Dropped the change of the name of an already existing test, to not
          distract the reviewers, as suggested by Eric Sunshine [4]
        - Renamed the first added test, as suggested by Eric Sunshine, [4] to
          make it consistent with the expected way for naming setup tests
    
    Changes in v2:
        - All new tests and one already existing test reworked according to
          Eric Sunshine's review suggestions; [1][2]  the already existing
          test was reworked a bit to ensure consistency
        - Added a Helped-by tag
