Also fix test_mousewheel: do not skip a check which was broken due to incorrect
delta on Aqua and XQuartz, and probably not because of `.update_idletasks()`.
The word 'dependent' is both an adjective and a noun. A 'dependant' is a British alternative spelling for the noun form. In idlelib.sidebar, 'OS-dependant' is an adjective and clearly wrong. In 'Using', 'dependant' as a noun would be acceptable in Britain, but we use American spellings in Python docs.

Integer to and from text conversions via CPython's bignum `int` type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds.

I wrote up [a one pager for the release managers](https://docs.google.com/document/d/1KjuF_aXlzPUxTK4BMgezGJ2Pn7uevfX7g0_mvgHlL7Y/edit#). Much of that text wound up in the Issue. Backports PRs already exist. See the issue for links.
If one selects whole lines, as the sidebar makes easy, do not
add an extra line. Only move the end of a selection to the
beginning of the next line when not already at the beginning
of a line. (Also improve the surrounding code.)
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.

Remove call to macosx.setupApp, which calls macosc.overrideRootMenu, which modifies
the menus, which results in two failures in the second round of the leak test.
