readline − improve readline editing
A support package that tries to make editing with readline easier. At the moment, it reacts to clicking shift-left mouse button by trying to move the text cursor to this position. It does so by generating as many cursor-left or cursor-right keypresses as required (this only works for programs that correctly support wide characters).
To avoid too
many false positives, this is only done when:
− the tty is in ICANON state.
− the text cursor is visible.
− the primary screen is currently being displayed.
− the mouse is on the same (multi−row−)
line as the text cursor.
The normal selection mechanism isn’t disabled, so quick successive clicks might interfere with selection creation in harmless ways.
