Pass an array as an argument

[cognitom]

To pass an array of streams to merge-stream, we have to write like below, now.

var gulp = require('gulp');
var merge = require('merge-stream');

gulp.task('css', function(){
  var tasks = [/* some tasks */];
  return merge.apply(null, tasks);
});

But it seems not intuitive for beginners. I'd like to change it little bit like below. How about?

return merge(tasks);

I've just added a small test to this PR.

In another example, it would be nice to write return merge(tasks); instead of return es.concat.apply(null, tasks);.

gulp.task('scripts', function() { 
   var folders = getFolders(scriptsPath);
   var tasks = folders.map(function(folder) {
      return gulp.src(path.join(scriptsPath, folder, '/*.js'))
        .pipe(concat(folder + '.js'))
        .pipe(gulp.dest(scriptsPath))
        .pipe(uglify())
        .pipe(rename(folder + '.min.js'))
        .pipe(gulp.dest(scriptsPath));
   });
   return es.concat.apply(null, tasks);
});

LGTM, but I'd prefer it if the array handling logic was moved into add so that the merge and add interfaces are consistent. Also, by putting it into add supporting arbitrarily nested arrays should be trivial.

@grncdr Exactly! Thanks for your reviewing. I've just tried to move the logic into add :-)

LGTM, thanks for the contributions :+1:

published in 0.1.5 - I was having some sort of weird network glitch and 0.1.3 and 0.1.4 may not work...

Thank you for your quick merge ;-)
