SA1134 exception for auto-properties

[LukeOwlclaw]

SA1134 prevents attributes from sharing the line with other code.

Consider this line of code:

public bool? DisableCaching { get; [UsedImplicitly] set; }

[UseImplicitly] is a Resharper annotation to avoid "Auto-property accessor never used warning" (UnusedAutoPropertyAccessor.Global).

Making this auto-property span over three lines just to avoid SA1134 seems wrong:

public bool? DisableCaching { get;
    [UsedImplicitly]
    set; }

Disabling the rule also "costs" three lines:

#pragma warning disable SA1134
    public bool? DisableBundling { get; [UsedImplicitly] set; }
#pragma warning restore SA1134

Can we have an exception for SA1134 for this case (like we already have for attributes for (type) parameters)?
