Subject: bug#23303: 24.5; [PATCH] term.el doesn't support absolute column movement

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.
