Anonymous-record-types omission

Tom Lane found an omission in the committed anonymous type code. The
coldeflist in the FROM clause was not being dumped by ruleutils.c. The
attached patch fixes this. Example:

-- before --

regression=# \d pg_settings
View "pg_catalog.pg_settings"
Column | Type | Modifiers
---------+------+-----------
name | text |
setting | text |
View definition: SELECT a.name, a.setting FROM pg_show_all_settings() a;
Rules: pg_settings_u,
pg_settings_n

-- and after --

test=# \d pg_settings
View "pg_catalog.pg_settings"
Column | Type | Modifiers
---------+------+-----------
name | text |
setting | text |
View definition: SELECT a.name, a.setting FROM pg_show_all_settings()
a(name text, setting text);
Rules: pg_settings_u,
pg_settings_n

Also included is the related adjustment to expected/rules.out. If there
are no objections, please apply.

Thanks,

Joe
