While the `SELECT FOR UPDATE`
[https://dev.mysql.com/doc/refman/8.0/en/select.html#idm45705194357888
documentation now mentions the] `OF` option I
[https://www.oracle.com/search/results?Ntt=%22FOR%20UPDATE%20OF%22&Dy=1&Nty=1&cat=mysql&Ntk
=SI-ALL5 couldn't find a single entry in the release notes] so I'm not
sure which version of MySQL supposedly added support for it.
All the `tests/select_for_update` tests happen to pass when setting
`has_select_for_update_of = True` even on MySQL 5.5 so I'm not sure if
this was always supported and never documented or if the syntax was always
allowed and they just recently added support for it? Only the MySQL 8
documentation mentions it though.
In all cases it seems like the feature should be allowed since all
supported versions of MySQL allow it.
