Lines differing only in whitespace compare equal, so a reindent or a CRLF/LF normalization produces no hunks and drops the file from --brief entirely. Comparison only: a line that does survive is emitted with its original bytes.

--brief reads content under -w, which it otherwise never does, and runs the same unified() the hunk path runs so the two cannot disagree about whether a file changed. A no-hunk result now claims 'mode changed' only on real byte equality -- with -w it also means a difference that was ignored. closed check-in: 23784ef673 user: dmestas tags: diff-ignore-ws
