Hello and happy holiday hacking. Does the read builtin stand to benefit from \[ and \] denotation ala $PS1 and friends? Here is a quick example:

read -erp "$( tput setaf 2 )NEW:$( tput sgr0 ) "

Fill the line with “0123456789ABCDEFGH” and try deleting some of it. I have attached a small demonstration.

Thank you.
