POSIX Issue 8 will be obsoleting %b (escape sequence interpolation) so
that future Issue 9 can change to having %b (binary literal output)
that aligns with C2x. But since escape interpolation may still remain
useful, POSIX suggested %#s (which is undefined in all versions of C)
as a possible
be easier (less shell escaping needed). Is there
any interest in a patch to coreutils or bash that would add such a
synonym, to make it easier to leave that functionality in place for
POSIX Issue 9 even when %b is repurposed to align with C2x?
