Base for gulp.src is empty if working directory has braces

Relative gulp version: 4

Create any directory with brackets i.e “gulp (brackets)”

• create readme.md file
• create simple gulpfile

const gulp = require('gulp');

gulp.task('default', function () {
  return gulp.src('readme.md')
    .pipe(gulp.dest('dist'));
})

• run gulp

Actual result: In directory dest we can see readme.md inside “gulp (brackets)” directory

Expected result: In directory dest we can see readme.md file

It seems that it is caused by isGlob and globParent implementation where isGlob evaluates such folder name as glob…

// From is-glob
module.exports = function isGlob(str) {
  return typeof str === 'string'
    && (/[*!?{}(|)[\]]/.test(str)
     || isExtglob(str));
};

// From glob-parent
module.exports = function globParent(str) {
    str += 'a'; // preserves full path in case of trailing path separator
    do {str = path.dirname(str)} while (isglob(str));
    return str;
};

// From glob-stream :
var basePath = opt.base || globParent(ourGlob) + path.sep;

Thanks to the debugging by @lukaskostial / @heikki / @stevelacy and great work by @doowb this has been fixed in v5.3.3 of glob-stream
