a2baf3a2e5 Make sure aggregate functions can take any number of arguments up to the 
limit imposed by SQLITE_LIMIT_FUNCTION_ARGS.  Ticket #3179.  Modify
the group_concat() function to take an unlimited number of arguments in
order to facilitate testing this behavior. (CVS 5233)

it occurred.  The quick.test script runs on Linux with no errors and
no leaks. (CVS 4273)
