so it is.  yet still irrelevant.  the GNU library defines behavior explicitly:
https://www.gnu.org/software/gnulib/manual/html_node/The-Backslash-Character.html#The-Backslash-Character

and it still doesn't explain why every version from bash-3.0 through bash-4.2 
behaves the same but bash-4.3 does not.  the release notes specifically call 
out backslash changes to make things "more consistent behavior".  i don't 
changing the behavior of the example i posted makes sense.
