Not easily, since the error messages indicating different kinds of
failure for a given file don't follow a standard pattern.  Some
approaches:

1. Write a humongous sed script to match all the error messages and
extract the filenames.

2. Use --log-file, and look at what files are *not* itemized in the log.
(Most failures, but evidently not certain attribute-related failures,
will cause a file to be omitted from the log.)

3. The most pragmatic approach: rerun rsync with --dry-run and look at
which files are still itemized as different.
