Summary: Checksum option does not work as expected when
append-verify is used
Product: rsync
Version: 3.1.3
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5
Component: core

Checksum option does not work as expected when append-verify is used. I can see
that checksums are created for all files but they are not synced.
rsync sample files to remote site:
# rsync -azhcv --append-verify --progress --stats .

Now i use hexcurse and change one of the source files - just flip some bytes.
As -c option is present I would expect that rsync detects that one file has
changed and updates it accordingly. I run rsync again - no files are synced - I
can confirm it by manually checking files' hashes.
