- If a hunk fails to apply to a file, patch discards all changes to
- that file and prints the failed hunk to stderr.
+ This version of patch only handles unified diffs, and only modifies
+ a file when all all hunks to that file apply. Patch prints failed
+ hunks to stderr, and exits with nonzero status if any hunks fail.
