Subject: Why does default shell prompt PS1 contain newlines (\n)?
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

After installing "plain vanilla" cygwin I noticed, that default definition of PS1 from /etc/bash.bashrc contains newline characters '\n':
     # Set a default prompt of: user AT host and current_directory
     PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '

This does immediately lead to the strange effect, that shell (bash) in interactive terminal window (C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico -) always advances 2 lines on every single CR.

This definition seems to be around pretty long already, as it is mentioned in several discussions on superuser &c. There is probably a very good reason for this - however, I could not figure out on my own, neither found any rationale in FAQ. Would be grateful for short explanation - thanks in advance.
