Leading dot on glob leads to unexpected results

It looks like the glob and regex matchers return true on empty streams. When I run the following tasks on a directory with no scss files:

gulp.task('styles', function () {
  return gulp.src(['app/styles/*.scss'])
    .pipe($.if('*.scss', gulpDebug() ))
    .pipe(gulp.dest('.tmp/styles'))
});

gulp.task('styles', function () {
  return gulp.src(['app/styles/*.scss'])
    .pipe($.if(/scss$/, gulpDebug() ))
    .pipe(gulp.dest('.tmp/styles'))
});

gulpDebug is fired both times.

This is mostly an issue when running gulp-changed along with a task that takes a while to spin up or errors with an empty stream.

I didn't test function conditions, so not sure what happens there.

This is an intriguing scenario. Thanks for the repro steps. I'll take a look.

No prob, and thanks! I dug into it a bit, but the function that does the matching is passed pretty deep into dependencies, debugging was beyond my ken.

Turns out this is the fragile nature of passing things into minimatch that start with a dot. Changing it to ./**/*.scss seems to resolve the symptom. Leaving this open as that's hardly a great user experience.
