Fix style of translatable string split across multiple lines. (PR #11092)
Fix-up of PR #10941
Finding the appropriate code style for a lengthy translatable string along with its required translators comment might not be obvious, even for some of our most seasoned contributors.
This problem has led to discussion about various attempts in PR #10941 and the raise of issue #11071.
PR #10941 finally resigned by disabling line length checks on a line of the patch.
However, as pointed out in a comment on #11071, a styling that complies both with line length and translators comment could finally be found.
