cron(8): openlog: ProgramName -> "cron"

[Andrew Pantyukhin]

Hello!

cron(8) is one of the rare services that puts something complicated in
ident (aka progname aka programname)  field of the syslog messages it
sends: /usr/sbin/cron[PID]. Would anyone be against changing it to
just "cron" to ease filtering with stock and third-party syslog
daemons, expecting no ":", "[", and "/" in the field?


Best,
Andrew
