[Feature request] Automatic unindent

[99991]

Editors automatically indent the next line to the level of the current line, but models are not able to automatically unindent the line, so they spew garbage instead. Example:

def add_lists(a: list[int], b: list[int]) -> list[int]:
    c = []
    for ai, bi in zip(a, b):
        c.append(ai + bi)
        ... # there is nothing useful to generate here at this indentation level

The best fix would probably be to finetune the models so they can fix indentation, but a simple workaround would be to start generating a few characters earlier, especially if the previous characters were all tabs or spaces.

I would like to have a setting to start predicting n spaces earlier.
