--- Comment #1 from François Gouget  ---
Adding echo %time% traces in test_builtins.cmd shows it is spending:

* 33 s in chain success ---> Testing 'set'
* 16 s in for /R  ---> for /R passed
* 21 s in individual operations ---> precedence and grouping
* 13 s in variables ---> quotes
* 13 s in quotes ---> whitespace are ignored between double char operators

Which is 96 seconds for a 159 seconds total runtime. So there is also quite a
bit that is spread around.
