[Bug 1239205] [NEW] bashrc: Please add newline to default PS1 bash prompt

[A. Eibach]

Public bug reported:

This is more an enhancement request than a "bug" report, but it's not a
question either :)

This is from the vanilla bashrc on my Lubuntu Saucy beta: (bash
v4.2-5ubuntu3)

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

which aroused the following problem: when cat'ing a file, and a second one just afterwards, it was impossible to determine (when scrolling in e. g. xterm)  where the one file ended and where the second file began.
Output was like this:

andy at somewhere:~$ cat silly0
foo
foo
bar
andy at somewhere:~$ cat silly1
bar
foo
foo
andy at somewhere:~$ 

Actually, it must be noted that each file were a few hundred lines long,
so scrolling was mandatory.

The result I'd like to get is:

andy at somewhere:~$ cat silly0
foo
foo
bar

andy at somewhere:~$ cat silly1
bar
foo
foo

andy at somewhere:~$

to let the different outputs "breathe" a little. This little amendment
to the default bash prompt improved a lot on my side, and reduced the
timely efforts of finding beginnings and endings of output.

Hence, the default line ought to be this:

if [ "$color_prompt" = yes ]; then
    PS1='\n${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='\n${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

Please think of users totally new to Ubuntu or its remixes who have no
idea where to "fix" this. This should be default.
