bpo-44026: Include interpreter's typo fix suggestions in message line
for NameErrors and AttributeErrors. Patch by E. Paine.
bpo-41611: Avoid occasional uncaught exceptions and freezing when using
completions on macOS.
bpo-37903: Add mouse actions to the shell sidebar. Left click and
optional drag selects one or more lines of text, as with the
editor line number sidebar. Right click after selecting text lines
displays a context menu with 'copy with prompts'. This zips together
prompts from the sidebar with lines from the selected text. This option
also appears on the context menu for the text.

Patches by Terry Jan Reedy and Pablo Galindo

IDLE dialog windows as dialogs.

masquerade rules or failure displaying complex colored (non-ascii) characters.
bpo-43283: Document why printing to IDLE's Shell is often slower than
printing to a system terminal and that it can be made faster by
pre-formatting a single string before printing.

Debugger is active, to prevent hang or crash. Patch by Zackery Spytz.
