For those who may be interested, I found the flaw after reading
O'Reilly's "bash Cookbook"

This:

PS1='[\u@\[\e[0;31m\h\e[0m]\]:\W\$ '

Should be:

PS1='[\u@\[\e[0;31m\]\h\[\e[0m]\]:\W\$ '

EXPLANATION: "\e[0;31m" has to be enclosed within escaped brackets like
"\[\e[0;31m\]" because it's a non-printing character. Similarly,
"\e[0m]" must be enclosed within escaped brackets like "\[\e[0m]\]".
