CentOS - Apr 2015 - CentOS-6.6 - wget $? returns 0 when invalid protocol used

Can someone enlighten me why this:

wget --quiet --no-check-certificate
ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf
; echo $?

returns this:
0


When wget --no-quiet says this:


wget --no-quiet --no-check-certificate
ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf
; echo $?

ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf:
Unsupported scheme `ttps'.

0


Is not an unsupported scheme an error in much the same fashion as an
invalid URI?  Should it not return an non-zero value in '$?' ?


wget

; echo $?
