Re: pkg/41423: CenterIM unusable: ignores several keys (like enter)

Ah ok. Well, in the end, it should not really matter. I haven't got it to
work with base's curses, thus the INCOMPAT-line and ncurses.

he he, ok. Well, if it's just that, I don't care: work-around "use
different bg-color" is easily done :)

If I can help, I'll do it :)
And yes, it looks quite consistent.

Now that you are mentioning terminal-types like xterm...I tried different
$TERM values, e.g. vt100 and xterm, and the behavior of the keys never
changed. I don't know if this information is helpful, but since I tried
that, I thought it couldn't hurt being mentioned :)
