I guess this is an analog of making color.ui default to "auto" we
did earlier. After having shipped with a more conservative default
while letting willing users experiment/experience to help us get the
kinks out of the "auto" setting, it probably is about time to flip
the default.

This ensures that an explicit --no-decorate from the command line
does give "none" output, which we failed to do so far, and is a good
change.  Don't we also need a _new_ test to ensure that "auto" kicks
in without any explicit request?  Knowing the implementation that
pager-in-use triggers the "auto" behaviour, perhaps testing the
output from "git -p log" would be sufficient?
