Warning: Replacing docs

[GregPlowman]

I'm getting these warnings with FileIO v1.2.0.
Affects Julia versions v1.0.5, v1.1.1, v1.2.0, v1.3.0.

┌ Warning: Replacing docs for `FileIO.filename :: Tuple{Any}` in module `FileIO`
└ @ Base.Docs docs\Docs.jl:223
┌ Warning: Replacing docs for `FileIO.file_extension :: Tuple{Any}` in module `FileIO`
└ @ Base.Docs docs\Docs.jl:223

This is a Julia bug. Fixed in JuliaLang/julia#34125

[ExpandingMan]

Is there anything that can be done in FileIO to silence this warning? This won't be fixed in 1.3.1 so clearly it'll be a while.

Someone can delete the @nospecialize annotations. I'm not against this but am traveling so won't do it myself.
