Correctly treat all assignments with bogus trailing comments. Before this patch, automake would silently fail to diagnose and to copy into the output those variable assignments which are preceded by a comment, and end in backslash newline comment. * automake.in (read_am_file): When determining whether an escaped newline followed by a comment is an error, correctly use the parser state, not the contents of a saved comment, which could still be carried over from a comment before an assignment. * NEWS: Update. * tests/commen11.test: New test. * tests/Makefile.am: Update.
