# Generate an anonymous sub that can be used to filter the kstats we will
# display.  The generated sub will take one parameter, the string to match
# against.  There are three types of input catered for:
#    1)  Empty string.  The returned sub will match anything
#    2)  String surrounded by '/' characters.  This will be interpreted as a 
#        perl RE.  If the RE is syntactically incorrect, an error will be
#        reported.
#    3) Any other string.  The returned sub will use gmatch(3GEN) to match
#       against the passed string
