I do something similar, but I don't change PS1 in the prompt command.
My prompt does end up on two lines, but when I'm in a long path at
least the command edit area stays large.
PS1='\[\e[1;32m\]\u\[\e[1;33m\]@\h\[\e[0m\] \$ '
PROMPT_COMMAND='echo -e "\e[1;36m$(date "+%a %d%b%y %H:%M:%S")
\e[1;33m${PWD/${HOME}/~}\e[0m"
