Might as well open an issue to track the things that should be sent to the log.

Currently implemented:

a - aborted run recovery
c - rsync calls
C - rsync call completions
e - minor errors
E - serious errors
l - lock contentions
r - run start
R - run end

• Need to add statistics to R, after grepping them out from the rsync stats output.
• add f - all transferred files (grep out of rsync log)
• add d - all deleted files
