OPTIND not reset and not local to the function

Description of problem:
It is a documented behaviour but not what the user(me) expects.
I have 2 complex functions that do parameter parsing with the getopts
built-in command. OPTIND is used to keep the number of next parameter to
parse. It is reset to 1 whenever a new shell is invoked.
I makes more sense to be reset to 1 *for the function* when called so that
function's parameter parsing is independent.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
function1 -p x -f y #parameters parsed correctly
function2 -g j -d l #no parameters detected
function1 - parameters parsed correctly
function2 - no parameters detected
This is because OPTIND is a global variable modified by function1 during
both functions have parameters parsed correctly
At the beginning of the function put "local OPTIND=1".
What are you expecting it *is* documented behavior?
That is a feature request. I can't see any sense in current behavior.
Or will you point me to the bash bug tracking system if any?
