Add Commands to the exported modules
Export Exit, rather than the mistaken ExitCode
Ignore any data file, including any suffix
Rewrite the test suite to use the standard Shake thread pool, massively increased robustness, especially to exceptions, and much simpler
Tweak the docs test so it imports the module under test, removes a few special cases
Add shakeLineBuffering
If shakeThreads==1 always use a deterministic thread pool
Start documenting Shake.Command
Make repeated --verbose keep increasing the verbosity
Put out some messages when running a command, makes --verbose print full command lines
Make Loud print out the full path, but not also the traced command
Add Chatty verbosity, for what used to be loud
Tweaks to the Command module
Replace the C example from sys to cmd
Fix up the docs test for the Command module
Print traced messages the other way round (looks more natural)
