Bash 5.2.15 (Debian 12) will produce erroneous output when PS1 contains
escape sequences. It will also misplace the cursor and corrupt the state
of the current line.
To replicate this issue:
1. Modify PS1 to contain one or more ANSI escape sequences, for example

The trouble with using an option flag to printf(1) to toggle the meaning of
%b is that you can't then mix format specifiers for binary literals and
backslash escape expansion within the same format string. You'd just have
to call printf(1) multiple times, which largely defeats the purpose of a
form

Thanks for the suggestion, but adding \] does not really fix the
problem, it just masks it in many cases (better than nothing).
Try:

And for those who have been following this issue, the new text for
the forthcoming POSIX version has removed any mention of obsoleting
%b from printf(1) - instead it will simply note that there is will be
a difference between printf(1) and printf(3) once the latter gets its
version of %b specified
