bug#14299: Incorrect output of `printf "\\n"`

[Pavel Elkind]

Dear developers,

I found the following potential bug in printf (version 8.17).

Actual result: 
`printf "\\n"` prints a newline caracter.

Expected result:
`printf "\\n"` prints a sequence of two individual characters, '\' and 'n', 
like '\n',  but  not a newline character.

Please address the above issue,

Many thanks,
Pavel
