Question about help information for the printf command

[2477441814]

Dear team,


when I invoke 'help printf' in terminal to view help manual, It shown me '%b %q 
%(fmt)T' is an addition to printf(1) and printf(3), The online version of bash 
manual from (http://www.gnu.org/software/bash/manual/bash.html) does samely 
describe.  but from GNU coreutils 8.22 which installed on my computer, It had 
support '%b', and GNU coreutils 8.31 support both '%b' and '%q', so I think 
it's necessary to modify description.


I hope you can consider my suggestion.


Best wishes,
YuLiang Liu
