   directory only, use the pattern "*.txt". To match any file ending
   in ".c" anywhere in the repository, use the pattern "**.c".
 
+  There can only be one filter command for each filter pattern. 
+  Specifying another filter command for a filter pattern overrides the 
+  previous. Note that all the filter commands for all matching filter 
+  patterns are applied to all files in an undefined order.
+
+  The filter command "!" can be used to disable a filter pattern as if 
+  it hadn't been defined.

   The filter command can start with a specifier, either "pipe:" or
   "tempfile:". If no specifier is given, "pipe:" is used by default.
