Subject: [PATCH 1/3] plugins/chucknorris: Add automatic updating of the

 function to provide a scope for the local variable.

Subject: [PATCH 3/3] chucknorris: check for strfile dependency Gives a better
 error message than "command not found: strfile", because it's not obvious to
 many users that strfile is part of fortune. Also handles the weird /usr/sbin
 install location for strfile on Cygwin.
