Overzealous `uninlined_format_args`

Description

Consider this snippet from a match statement:

Self::TemplateSwitchExit {
    entrance_reference_index,
    entrance_query_index,
    template_switch_primary,
    template_switch_secondary,
    primary_index,
    anti_primary_gap,
} => write!(
    f,
    "TemplateSwitchExit({}R, {}Q, {}P, {}G, {}, {})",
    entrance_reference_index,
    entrance_query_index,
    primary_index,
    anti_primary_gap,
    template_switch_primary,
    template_switch_secondary
),

Clippy wants me to put all format args into the string, but that would make the string incredibly long. cargo fmt would not break up the string into multiple lines either.

I think the code is easier to read like this. Clippy should not suggest inlining format args if the resulting string gets too long.

Start at the uninlined_format_args lint and reproduce the report with the provided match statement and write! call. The work is done when the lint avoids suggesting inlining that would make the format string excessively long, with regression coverage for this case.
