When looking backwards through a long terminal session history (e.g.,
using shift-pageup/pagedown), it can be hard to see where the output
from each command starts. An easy way to improve this is to make
the bash prompt be in boldface: essentially, run "tput bold" before
the prompt, and "tput sgr0" after it. Something like this should
work:

    PS1="\\[$(tput bold)\\]$debian_chroot\\u@\\h\\$ \\[$(tput sgr0)\\]"

Would it be acceptable to do this for the default bash prompt?
