[Sonic-Amiga]

Recognize and correctly report Backspace key to applications.

Hello! I am working on a ESP8266 project and caught a problem with "make menuconfig": Backspace key in config utility does not work correctly. This patch contains a fix, i hope you find it useful.

I also have posted a bug in official tracker: http://savannah.gnu.org/bugs/index.php?64292

Thanks. Let's wait a bit to see if upstream responds.

[Sonic-Amiga]

@lazka Seems it doesn't. I'm not even sure it's a correct upstream.

Hello! The upstream has released a new version, ncurses-6.4-20230708 . The bug has been fixed.

[mmuetzel]

I opened #17759 to update to that version.

@Sonic-Amiga: Could you please check if the build artifact from that PR fixes the issue reported by you?

[Sonic-Amiga]

It does because i built MinGW version of the new archive locally for testing in absolutely the same way.
