The shell just prints the prompt where ever the cursor was left. That's 
quite common, the only exception I know is zsh, which moves the cursor 
to the start of line if the previous command didn't leave it in the left 
edge.

A simple workaround would be to add '\n' at the start of the prompt, but 
it would then print an empty line above the prompt for every command 
that does properly finish the output with a newline. Some might find 
that ugly.

It might be possible to check for that manually in PROMPT_COMMAND. 
Something like this seems to mostly work for me in interactive use, 
though it's rather stupid and will probably break down at some point.

   prompt_to_bol() { local pos; printf '\e[6n'; read -sdR pos;
       [[ ${pos#*;} != 1 ]] && printf '\e[30;47m%%\n\e[0m'; }
   PROMPT_COMMAND=prompt_to_bol
