SourceMapIn for globbed files should support multiple sourceMapIn's

[tigerhawkvok]

Example:

module.exports = (grunt) ->
  grunt.loadNpmTasks("grunt-contrib-uglify")
  grunt.loadNpmTasks("grunt-contrib-coffee")
  grunt.initConfig
    pkg: grunt.file.readJSON('package.json')
    uglify:
      options:
        mangle:
          except:['jQuery']
      dist:
        options:
          sourceMap:true
          sourceMapIncludeSources:true
          sourceMapIn: (file) ->
            "scripts/maps/#{file}.map"
        files: [
          expand: true
          flatten: true
          cwd: "scripts/"
          src: ["*.js"]
          dest: "scripts/"
          ext: ".min.js"
          ]
    coffee:
      compile:
        options:
          join: false
          sourceMapDir: "scripts/maps"
          sourceMap: true
        files: [
          expand: true
          flatten: true
          cwd: "coffee"
          src: "*.coffee"
          dest: "scripts/"
          ext: ".js"
          ]
  grunt.registerTask("compile","Compile coffeescript",["coffee:compile","uglify:dist"])

This should work, reading in each sourcemap for each coffeescript file, and using the correct source map. Instead, an error explicitly acknowledging this lack of support comes up.

I would love to see this implemented. I think we could do it by allowing that variable to be an array of strings or a glob.

Would be nice. I'm using both coffeescript as well as concat. It's a bit of a pain that you can't pull both the sourcemaps in.

Would be helpful. What i'm trying to do is take a bunch of JS files and CoffeeScript files, compress them into one .js file, and have all the proper sourcemaps generated so that it can be easily debugged.

FYI I found a tool that does exactly that. grunt-contrib-mapcat. Works great!

+1. This is very frustrating.
