Log Message:
rsync: update to 3.2.6.

### BUG FIXES:

- More path-cleaning improvements in the file-list validation code to avoid
  rejecting of valid args.

- A file-list validation fix for a [`--files-from`](rsync.1#opt) file that ends
  without a line-terminating character.

- Added a safety check that prevents the sender from removing destination files
  when a local copy using [`--remove-source-files`](rsync.1#opt) has some files
  that are shared between the sending & receiving hierarchies, including the
  case where the source dir & destination dir are identical.

- Fixed a bug in the internal MD4 checksum code that could cause the digest
  to be sporadically incorrect (the openssl version was/is fine).

- A minor tweak to rrsync added "copy-devices" to the list of known \ 
args, but
  left it disabled by default.

### ENHANCEMENTS:

- Rename `--protect-args` to [`--secluded-args`](rsync.1#opt) to make it
  clearer how it differs from the default backslash-escaped arg-protecting
  behavior of rsync.  The old option names are still accepted.  The
  environment-variable override did not change its name.
