bug#28372: getconf help info

[Jonny Grant]

Hello

I noticed two different types of help output. Examples below. The later 
seems a little hard to comprehend.  Could they be unified?

$ getconf
Usage: getconf [-v specification] variable_name [pathname]
       getconf -a [pathname]


$ getconf --help
Usage: getconf [-v SPEC] VAR
  or:  getconf [-v SPEC] PATH_VAR PATH

Get the configuration value for variable VAR, or for variable PATH_VAR
for path PATH.  If SPEC is given, give values for compilation
environment SPEC.


$ getconf --version
getconf (Ubuntu GLIBC 2.23-0ubuntu9) 2.23


Expected:
Also the addition of

       getconf --help Show this help
       getconf --version Show version number


Could you keep my email address in replies please

Thank you
Jonny
