[orca-list] double echo by character in gnome-terminal

[Pavel Vlček <vlcekpavel93 gmail com>]

Hi,

I set enable enable echo by character. All is working, but in Terminal, 
Orca says all letters twice. For example I write s, Orca says s s. I 
write u, Orca says u u. Is it ok? Orca 3.22.2, gnome-terminal 3.22.1.

Thanks,

Pavel
