Preventing "no matches found:"

[Tim McNerney <yargo@xxxxxxx>]

Is there some way to indicate that patterns may have no matches? I am  
doing a cron job that does cleanup of all files older than a certain  
time and have a line like:

  rm ~/log/**/*.log(m+7)

and would like to avoid the message:

  no matches found: ~/log/**/*.log(m+7)

by somehow indicating, either through a setopt or a parameter for (),  
that no matches is not an error.

Thanks.
