There appear to be several new functions that have been added to po/Makevars but not recognised by "make po-check" (rule in top-level Makefile.am) to make a file contain translatable strings:
message_list_document_error message_list_document_warn (others?) This means the output of "make po-check" may be incorrect as to which files should be listed. I won't have any more time tonight to try to fix this but will get to it in coming days if nobody else does first.
