Hi Chet,

unfortunately, there's additional problem with bash
multibyte behavior, which is specific to sparc.

When using bash patch level <49 on sparc in multibyte,
pressing right arrow at the end of the line moves
the cursor one character left.

When using bash patch level 49 on sparc in multibyte,
pressing right arrow at the end of the line moves
the cursor two characters left.

Attached patch does remove the issue, but may
not be the core problem... I'd be grateful for
comments.

Thanks & regards,
hnhn
