Some of the commands I run seem to take a long time, but also varying 
amounts of time.

I'd like to prefix "time" to every command that runs.  So that,

when I type:


     % make long-running-target

I'd like to see the equivalent of:


     % time make long-running-target

     ...

     make long-running-target     0.00s user 0.00s system 66% cpu 0.004 
total


I thought preexec() might help:


     preexec() {

         set $3

         eval time "$@"

     }


but this ends up running the same command twice, once timed, and once 
without.
