fix: cursor position error when display completion (#337)

Triggering completion when cursor is in command might lead to cursor
position error cause patch of bug 67102 trims trailing '\b' which
is not suitable for this case. As 67102 is not totally resolved(I
can still reproduce this), we just simply revert the modification.
