Delete key changed its behavior

[Ionutz Borcoman <borco@borco-ei.eng.hokudai.ac.jp>]

Hi,

After installing some packages from Debain-JP, my delete and backspace
keys changed their behavior under X. Now they delete the character in
front of the prompt. Even Netscape behaves like this. Can somebody
please tell me where should I make the changes ?

TIA,

Ionutz
