Missing documentation of the integer range (declare -i)

[H.-Dirk Schmitt]

Checked against:  GNU bash, Version 4.4.12(1)-release (x86_64-pc-linux-
gnu) 

I carefully read the man page and find no definition of the defined
range of integer variables in bash.
see also:  `man bash |& grep -i integer`
