 *
 * ``` js
 * shExpMatch("http://home.netscape.com/people/ari/index.html", "*\/ari/*")
 *   // is true.
 *
 * shExpMatch("http://home.netscape.com/people/montulli/index.html", "*\/ari/*")
 *   // is false.

 * @param {String} shexp is a shell expression to compare against.
 * @return {Boolean} true if the string matches the shell expression.
