Summary

Ive noticed that white spaces matter in the [columns] definition of <unique-constraint>.
I havent tested it for other lists but given the following example:

<!-- ... -->
<entity name="Vendor\Module\Model\Locale" table="locale">
        <id name="id" column="id" type="bigint" />
        <field name="countryCode" column="country_code" type="string" length="3" />
        <field name="languageCode" column="language_code" type="string" length="3" />

        <unique-constraints>
            <unique-constraint columns="country_code, language_code" name="locale" />
        </unique-constraints>

</entity>
<!-- ... -->

Running vendor/bin/doctrine orm:validate-schema then prints the following error:

  There is no column with name ' language_code' on table 'locale'.

In my opinion it should be possible to add whitespaces in [columns]-attribute for more readability.
