You can assign the desired string to a variable, then use typeset
to set alignment on it. For example:
PS1=$'${|typeset -R$COLUMNS REPLY="[$USER@$HOSTNAME:$PWD]";}\n'
Dissolved:
PS1='${|typeset -R$COLUMNS REPLY="[$USER@$HOSTNAME:$PWD]";}'$'\n'
Part 2 is just a newline. Part 1 is assigned literally:
${|typeset -R$COLUMNS REPLY="[$USER@$HOSTNAME:$PWD]";}
This is then evaluated every time PS1 is shown.
${| … ;} is a function block that evaluates to $REPLY. That is,
${| REPLY=x ;} is the same as $(echo x), except with less overhead.
typeset -R$COLUMNS makes a right-aligned space-padded variable.
The rest is just its content.

what? It's my right. It's my freedom of expression. Without that, we're
nothing but slaves." -- Johnny Rotten
