Now my root prompt, instead of being red, looks like:

That will be due to incorrect quoting. Which suggestion did you
implement? There were several.
What version of bash has the \[ \] characters to keep it from
counting chars?
All of them.
Try this *exactly* as I post it. I did test this. It probably isn't
optimal. But it does what you are asking. And it is only a slight
variation from what you are currently using.
_CRed=$(tput setaf 1) #Red
_CRST=$(tput sgr0) #Reset
_CBLD=$(tput bold) #Bold
_prompt_open=""
_prompt_close=""
---------------------------
_prompt=">"
[[ $UID -eq 0 ]] && {
_prompt_open="$_CBLD$_CRed"
_prompt_close="$_CRST"
_prompt="#"
}
PS1='\[$_prompt_open\]$(pwd "$PWD")$_prompt\[$_prompt_close\] ';

I had been using the version w/single quotes:
# _CRed='\[\033[31m\]' #Red
# _CRST='\[\033[0m\]' #Reset
# _CBLD='\[\033[1m\]' #Bold

Your version works better because I am slowing starting to understand.
My initial change added the above single quotes and nothing else. You
changed the PS1 string as well.
Going from:
PS1='${_prompt_open}$(spwd "$PWD")${_prompt_close} ';
to:
PS1='\[$_prompt_open\}$(spwd "$PWD")[$_prompt_close\] ';
So if I understand why the single quoted version didn't work
I'll probably understand why my final problem doesn't work (It's better!)
A string I didn't have in the example because I didn't think it pertinent,
was where the 'dashed line is, above', I had:
PUBLIC _disp_port=${DISPLAY/[^:]*:/}
Which doesn't display any hidden charcters, but no longer displays.
So what's the deal here...none of the vars-in-curls expand
but are changed to something different?
Since the above prints, (as well as the directory, and 2 character suffix
("> " or # ") print, should they also be included in the 'ignore' all chars
section?
Answer: (Nope... am in a line with about a 28 character prompt and it wraps
about 24 characters into the 2nd line back to the start of the 2nd line,
overwriting itself.... looking something like:
\}home/tools/../work/src[# 2345678901234567890123456789012345678901234567890123
0wrap around67890123456789
^column 0 where the 0 is
But this is very excellent...
What I don't understand is why you sub'ed in the square bracket...oh
nevermind...don't ned the curlies for simple var...oh...you did unquote the
path parth...must just be the DISPLAY part throwing it off...
