Generic parameter in value binding does require a space before the colon.

[nojaf]

In section Right-pad value and function argument type annotations, I believe there is an edge case to this rule.

let e<'t> : int =
    // a comment makes things multiline
    8

The space before the colon is necessary in this case to maintain valid code.

Yeah, this is an edge case, but I also think it shouldn't really be documented since it's such a rare thing to do. This is likely better served as a change to the parser itself to just allow this. I think this should just transfer over to dotnet/fsharp.
