vim31 - first char of function name should be upper

• vim에서 function을 정의할 때, function name의 첫번째 글자는 대문자(Upper letter)가 되어야 합니다.

function FunctionName()
endfunction

• :help user-function를 통해 이유를 확인해 보면 대략 “builtin function 과의 name confusion을 막기 위해서 user defined function의 경우는 upper case를 쓰도록 한다”인 것 같네요.

The function name must start with an uppercase letter, to avoid confusion with builtin functions. To prevent from using the same name in different scripts avoid obvious, short names. A good habit is to start the function name with the name of the script, e.g., “HTMLcolor()”.
