Default task inconsistencies with other grunt contribs

[brendanseabrook]

Hello,

Relatively new to this stack. One thing that just tripped me up was that when using other contribs (jshint, concat, uglify, copy), they all have an implicit 'default' task. Less is the only one I have encountered which requires a task level.

//Runs as default task
less: {
  default: {
    files: {
      "dist/css/foo.css": "style/foo.less"
     }
  }
}
//Runs as default or develop task
less: {
  develop: {
    files: {
      "dist/css/foo.css": "style/foo.less"
     }
  }
}
//Does not run anything. No warnings. No errors
less: {
  files: {
    "dist/css/foo.css": "style/foo.less"
  }
}

If someone could explain why this is that would be great. Thanks.
