code: function isAbsolutePathOrUrl(pathOrUrl) {
          return brackets.platform === "win" ? PathUtils.isAbsoluteUrl(pathOrUrl) : FileSystem.isAbsolutePath(pathOrUrl);
      }
docs: getModuleUrl returns different urls for win platform
  so that's why we need a different check here
  @see #getModuleUrl
  @param {!string} pathOrUrl that should be checked if it's absolute
  @return {!boolean} returns true if pathOrUrl is absolute url on win platform
  or when it's absolute path on other platforms
