By default, it preserves an inconsistent behavior of older Python
versions: packs the count into a 1-tuple if only one or none
options are specified (including 'update'), returns None instead of 0.
Except that setting wantobjects to 0 no longer affects the result.
Add a new parameter return_ints: specifying return_ints=True makes
Text.count() always returning the single count as an integer
instead of a 1-tuple or None.
It now always returns an integer if one or less counting options are specified.
Previously it could return a single count as a 1-tuple, an integer (only if
option "update" was specified) or None if no items found.
The result is now the same if wantobjects is set to 0.
Left click and drag to select lines. With selection, right click for context menu with copy and copy-with-prompts.
Also add copy-with-prompts to the text-box context menu.
