In the same ways as for blacklisting. In the process, move reporting of an unrecognised tag outside the global-data loop, as the tag might be, or start with, a global data tag; and also report the global data alongside the test-specific data. Indent the lines reporting tags, as this makes the structure of the lists more evident. Converted the tag argument to QLatin1String() to facilitate searching and matching. Updated documentation, including expanding on the option of specifying the data tags on the command-line. Drive-by: fixed a link in the documentation, removed a snippet that was nowhere used. [ChangeLog][QtTest] When specifying what tests to run on a QtTest command-line, it is now possible to include a global data tag in the same way as a function-specific data tag or in combination with it. Thus if the test reports itself as tst_Class::function(global:local), command-line option function:global:local will select that specific test and function:global will run all data-rows for the function on the given global data tag.
