Why in prompt.sh we need PROMPT_COMMAND="find_git_branch; find_git_dirty; $PROMPT_COMMAND"?

More specifically why we add the existing PROMPT_COMMAND making it grow?

Found it, PROMPT_COMMAND is a bash var that sets what to execute before PROMPT is dispalyed. We save potentially already altered PROMPT_COMMAND https://tldp.org/HOWTO/Bash-Prompt-HOWTO/x264.html
