While testing out a program I noticed it was misbehaving in M-x
ansi-term for the commands using the \e[0G sequence for moving the
cursor to column 0.  Apparently this is because it doesn't have any code
branch in `term-handle-ansi-escape' for this case.  I've attached a
patch to fix this deficiency.
