Works as well:

    Committer testing:

      $ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db

      Simply right click and pick "Copy selection", that at this point has
      just the first line, not expanded, then see what was copied by pressing
      shift+control+v on a terminal:

    Call Path,Object,Count,Time (ns),Time (%),Branch Count,Branch Count (%)
    ▶ simple-retpolin,,,,,,

      Ditto after expanding, i.e. the selection continues to be just one
      line:

    Call Path           Object   Count   Time (ns)   Time (%)   Branch Count   Branch Count (%)
    ▼ simple-retpolin

       Now select all the lines with the mouse and control+shift+v again:

    Call Path                     Object             Count   Time (ns)   Time (%)   Branch Count   Branch Count (%)
