ecpg: Reject multiple header items in GET/SET DESCRIPTOR Previously, ecpg accepted multiple descriptor header items in GET DESCRIPTOR and SET DESCRIPTOR, but generated broken C code when they were used. Although the grammar allowed this syntax, the implementation did not actually support it.
This commit tightens the ecpg grammar so the header form of GET/SET DESCRIPTOR accepts only a single header item, matching the implementation and preventing generation of broken C code. Also update the documentation synopsis accordingly. Backpatch to all supported versions.
