    ??? It takes up 30% of the initialization time.   I'm
confused.  If it isn't being used, how can it take up 1/3rd of the
startup time?


As for -P  -- that makes 'have' do what it was designed to do.  As it
is, it tests for the presence programs based on function and alias
definitions. It's supposed to check for the presence of the programs
in the PATH -- not functions and aliases.  But if you want it to remain
buggy, just change out the function and make the alias = to 'type'.
The use of -P is just to make it correct -- it doesn't affect the
performance improvement.
