Break string percent formatting like black

[konstin]

black:

template_params["lhs"] = "%s, %s" % (
    template_params,
    lookup_band_lhs,
)

template_params__lhs__ = "%s, %s" % (
    template_params,
    lookup_band_lhs,
)

ours:

template_params["lhs"] = (
    "%s, %s"
    % (
        template_params,
        lookup_band_lhs,
    )
)

template_params__lhs__ = "%s, %s" % (
    template_params,
    lookup_band_lhs,
)

@konstin Feel free to assign this to me. May take a bit as I have to get up to speed with the formatter, though.

I'm not sure if this is a good first formatter issue. Feel free to have a look but I expect that this fix requires good knowledge of the IR

You could coordinate with @dhruvmanila and implement a match case formatting.

Uh interesting, that's not what I expected would fix this
