Summary: nonstandatd behavior of example for command line parameters

Initial Comment:
In chapter "4.12 Silent Installers/Uninstallers" is
example how to read and parse command line parameters.
It expect that quotes will be in form:
"/USERNAME=guest". I think that correct quotes using is
/USERNAME="guest". Here is my macro for such parsing:
!macro FindParam params paramName
	${StrStr} $0 "${params}" "/${paramName}="
	StrCmp $0 "" no${paramName}
		Push $1
		Push $2
		StrLen $1 "/${paramName}="
		StrCpy $0 $0 "" $1
		StrCpy $1 $0 1
		StrCpy $2 " "
		StrCmp $1 '"' 0 notquo${paramName}
			StrCpy $2 '"'
			StrCpy $0 $0 "" 1
		notquo${paramName}:
		${StrStr} $1 $0 $2
		StrLen $2 $0
		StrLen $1 $1
		IntOp $2 $2 - $1
		StrCpy $0 $0 $2
		Pop $2
		Pop $1
	no${paramName}:
!macroend

Example of use:
	Call GetParameters
	Pop $9
	!insertmacro FindParam $9 "USERNAME"
	IfFileExists "$0" 0 skipUSERNAME

If already updating, why not make it recognize both?
