If the user passes a flag like `-version` to a program, it's more likely they mean `--version` than `-version:`, since there's no parameter passed. Hence, give delimited arguments a penalty of 1 if the user input doesn't contain the delimiter or no data after it. The motivation is that with this, lld-link can suggest "--version" instead of "-version:" for "-version" and "-nodefaultlib" instead of "-nodefaultlib:" for "-nodefaultlibs".
