Well, apparently Bob does use the copypasted line and it works for him ;)

Cron entries can be long single-line shell (/sbin/sh or user's shell?)
scripts, but anything over a line or two is impractical to maintain in
the crontab. The construct I do often use for optional programs is

* * * * *  [ -x /path/prog ] && /path/prog params

This does not generate tons of email complaints if the prog is not
installed in a particular zone, and allows to copypaste typical setup
files :)
