This needs a bit more adjustments to the tests.  Namely

 - t4202-log needs to pass --i-still-use-this because the test wants
   to check the output from the command when it functions;

 - t9300-fast-import needs to run "log --raw" instead, as the output
   from the existing call to "whatchanged" is simply discarded and
   not checked at all.  We could remove the call to "whatchanged"
   whose output is not even tested.

Also as we haven't listed the removal of this command in the 3.0
breaking changes document, we do not support WITH_BREAKING_CHANGES
build knob and test prerequisites yet.
