R devel - Dec 2025 - ^C does not clear the command being typed immediately in Rterm.exe on Windows

Hello,

In Rterm.exe on Windows, pressing ^C (Ctrl+C) does not clear *the command being
typed* immediately.
It does only after pressing ENTER.
However, it does terminate *the current process* immediately (i.e. without
pressing ENTER).

I observe the same behavior in R running from cmd.exe (not sure if it is
different from Rterm.exe).

Other escape sequences (e.g. ^U, ^K, ^R, ^D...) work as expected (i.e. as they
do on Linux).

Is it expected? Should it be reported to R Bugzilla?

FWIW, the use case is to clear (potentially malformed) multiline input.
^U and ^K works for single line input.
Am I missing something?

Thanks,
Thomas
