Sat 08 Aug 2020 05:38:53 AM UTC, comment #3: The problem of M-V M-Bsp sometimes seeming to enter nothing does not occur on xterm and rxvt. Apparently those emulators are fast enough to get stuff into ncurses' hands before nano calls wgetch() in non-blocking mode. But Xfce Terminal is just a bit too slow, getting it wrong about two thirds of the time. Probably other VTE-based emulators are too slow too, so... we need to add a little pause. |

To reproduce, run 'src/nano --ignore' and type: M-V M-Bsp.

Fixed in git, commit 5fab1e67.
On my machine (and with Xfce Terminal), pausing one millisecond is enough to get M-V M-Bsp to enter "^[^?" every time, but I've been generous and made it pause twenty milliseconds. The delay is nearly impercetible.
