		141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).

		147	To avoid too many false positives, this is only done when:

		219	This (experimental) perl extension implements OnTheSpot editing. It does
