[ngram] Ignoring regex with no delimiters

[amir.jad...@yahoo.com [ngram]]

I'm running count.pl on a set of unicode documents. Create a new file('token') 
which contains '\S+' in order to match any characters but space.
 Here is the output:
 

 ⇒  count.pl --ngram=1 --token=token ocount.txt Documents
 Ignoring regex with no delimiters: \S+
 No token definitions to work with.
 Type count.pl --help for help.
 

 What's the problem?!
