 Predicting what `patch' will do
 -------------------------------
 
    It may not be obvious in advance what `patch' will do with a
 complicated or poorly formatted patch.  If you are concerned that the
 input might cause `patch' to modify the wrong files, you can use the
 `--dry-run' option, which causes `patch' to print the results of
 applying patches without actually changing any files.  You can then
 inspect the diagnostics generated by the dry run to see whether `patch'
 will modify the files that you expect.  If the patch does not do what
 you want, you can modify the patch (or the other options to `patch')
 and try another dry run.  Once you are satisfied with the proposed
 patch you can apply it by invoking `patch' as before, but this time
 without the `--dry-run' option.
