line numbers for errors during macro expansion

[RichMorin]

Let's say my file (foo.jl) contains this code:

function main ()
  @printf("%s\n", "foo", "bar")
end

main()

Running this, I get a correct error message, followed by a broken stack trace:

ERROR: @printf: wrong number of arguments
 in include at boot.jl:238
 in include_from_node1 at loading.jl:114
 in process_options at client.jl:303
 in _start at client.jl:389
at /Volumes/Cutie/YAGO/bi_prep/foo.jl:0

Given that the error was in line 2 of the file, I think the error message should say so.

We'd like that too! This is the longstanding issue #1334.
