Report suppressions in the files no rule is ever run over A suppression that answers for nothing is an error, and that is what makes on-by-default with unlimited local escapes safe. Three files fell outside it, each one silent: a preprocessor's input, whose Haskell only exists at build time; an unclaimed file spelled with a preprocessor's extension, which the walk over unclaimed files did not look at; and any unclaimed file whose suppression was written in the bare form, which the walk's hand-written marker test did not match. The first two are now scanned, and the marker test is the parser's own rather than a second spelling of it, so a form one end judges and the other end misses cannot exist. A file under no source directory at all is outside what a package run reads and is still not covered.
