Remember that the user has to explicitly enable the TotalDownload option
to get this behavior. The pacman.conf man page will state that the
progress bar is still the percentage of the current file. If the user is
confused he can just go back to the old way.

pacman emits a carriage return (not a newline) after the download line
to return to the beginning of the line. I don't know how to print two
lines and return to the beginning of the first.

Here are two possibilities. I personally don't like either of them, but
I'll change it if I get enough pennies thrown at me again.

Proceed with installation? [Y/n]
