gulp.src should be a passthrough stream

This will alleviate the overusage of gulp-if

Example:

gulp.src('files/*.coffee')
  .pipe(coffee())
  .pipe(gulp.src('files/*.js'))
  .pipe(minify())
  .pipe(gulp.dest('dist'))

I usually use merge() from https://github.com/dominictarr/event-stream#merge-stream1streamn

return es.merge(
  gulp.src('./javascript/*.js')
    .pipe(minify()),
  gulp.src('./already-minified/*.js')
)
  .pipe(concat())
  .pipe(gulp.dest('...'));

Is there a current workflow for adding files to the stream midway? I need to conditionally add files based on the content of a previous file.
