macros checking is not working

[rssdev10]

I found that current implementation of macros checking is not working.

doc.jl-test generates an error:

s = """
@doc "this is a test"
f() = 0
"""
msgs = lintstr(s)
@test msgs[1].code == :W443

#AST Linting: Error During Test at /Users/rss/.julia/dev/Lint/test/doc.jl:16
#  Test threw exception
#  Expression: (msgs[1]).code == :W443
#  BoundsError: attempt to access 0-element Array{LintMessage,1} at index [1]

I added debug output into appropriate part of macros.jl:

    if istopmacro(ex.args[1], Core, Symbol("@doc")) && length(ex.args) >= 2 # see Docile.jl
        @show ex.args
        if isexpr(ex.args[2], :(->))
            @show ex.args[2].args[2]
            lintexpr(ex.args[2].args[2], ctx) # no need to lint the doc string
            return
        elseif typeof(ex.args[2]) <: AbstractString && length(ex.args) >= 3 && isexpr(ex.args[3], :call)
            # grandfather as a docstring of a previously declared function
            @show ex.args[2]
            return
        elseif (typeof(ex.args[2]) <: AbstractString ||
              isexpr(ex.args[2], :macrocall) && ex.args[2].args[1] == Symbol("@mstr")
             )
             @show ex.args[2]
            if length(ex.args) >= 3
                lintexpr(ex.args[3], ctx)
            else
                msg(ctx, :W443, "did you forget an -> after @doc or make it inline?")
            end
            return
        end
        return
    end

Results which I see for @doc macros are:

ex.args = Any[Symbol("@doc"), :(#= none:1 =#), :("this is a test"->begin
          #= none:1 =#
          f() = begin
                  #= none:1 =#
                  0
              end
      end)]
ex.args = Any[Symbol("@doc"), :(#= none:1 =#), :("this is a test"->begin
          #= none:1 =#
          f() = begin
                  #= none:1 =#
                  0
              end
      end)]
ex.args = Any[Symbol("@doc"), :(#= none:1 =#), "this is a test", :(f() = begin
          #= none:2 =#
          0
      end)]

See that ex.args[2] is always equal to :(#= none:1 =#). So nothing from the checks upper is working. Also I see very similar approach in other macros analysis.

So, what is it, is it specific of Julia 1.0 with adding of :(#= none:1 =#) expressions or forgotten removing of it from an array for analysis?
