Multiline function and subroutine hover displays duplicates

[gnikit]

If the argument list in a function or a subroutine spans multiple lines, hovering on an argument that is not on the scope start will show two signatures

MWE

   real function foo(val1, &
                     val2) &
                     result(val4)

      integer :: val1, val2
   end function foo

I think we should keep only the latter definition, which includes the variable name. Currently the default behaviour is to just show the type

I can't replicate this with the latest version

Was somewhat resolved in commit a3dce8d although now hovering over multiline arguments does not yield the right result

[gnikit]

This is because when we have multilines in fortls (&) we advance the line number prior to the AST parsing by

ine_no += len(post_lines)

which registers the scope at the END of the multiline as opposed to the very top

With fix applied to PR #217 this can no longer be replicated so I will be closing.
