Your error is in your subject line: getline rather than readline is used
on Windows. (readline was not written for Windows and depends on a
'curses' library not available for Windows terminals let alone RGui. A
considerable amount of time was spent trying to use it, unsuccessfully.)

That's the Windows way. And users of e.g. Emacs on macOS know how this
can cause awkward conflicts.

That's the Windows way: PuTTY is using an older Unix/X11 standard (not
so much used on Unix nowadays).

AFAIR that is part of the configuration you can save.
