rest.install and other .install files have malformed @defgroup doc blocks

At least two files in Core have malformed @defgroup doc blocks. The two I know about right now are:
core/modules/rest/rest.install
core/modules/serialization/serialization.install

Here is the documentation for what a @defgroup doc block is supposed to look like, from https://www.drupal.org/node/1354#defgroup :

/**
 * @defgroup group_identifier Topic title goes here
 * @{
 * Summary line for the group/topic goes here.
 *
 * Additional documentation paragraphs go here.
 */

(functions, classes, etc. that belong as members of the group go here)
...

But the @defgroup doc blocks in these two files (and possibly others that were copy/pasted from the same source) are missing the topic title. They instead look like this:

**
 * @defgroup updates-8.1.x-to-8.2.x
 * @{
 * Update functions from 8.1.x to 8.2.x.
 */

It should be an easy fix. They just need to have a title added to the first line of the @defgroup in the doc block. Please also look for other core/modules/*/*.install files that have defgroups with the same problem. There probably are some.
