Subject: setup.exe ignores unrecognized command-line arguments silently

Problem: setup.exe ignores unrecognized command-line arguments silently.

For example: the command line "setup.exe -P p7zip curl" installs p7zip 
but not curl.

Suggestion: Make it print a warning when it encounters an unrecognized 
command-line argument. So: "setup.exe -P p7zip curl" should print a 
warning: "warning: ignoring unrecognized command-line argument: curl"

Thanks,
Bart
