DOC: Add note about "* " prefix in CSV stats
The check_status field in the CSV stats output is conditionally prefixed
with "* " if a check is currently underway. This can trip tools that
parse the CSV output and compare against a well known list of values.
This commit just adds this bit to the documentation.
