Code of function 'factor' in R 3.4.0 (https://svn.r-project.org/R/tags/R-3-4-0/src/library/base/R/factor.R) still uses 'sort.list', not 'order'.

Thanks a lot for spotting and mentioning this!
I have now moved the entry to the NEW FEATURES of 'R devel'.

It could also go to 'R 3.4.0 patched --- to become R 3.4.1 at
around "useR! 2017" --- but it was not my change so don't know
how important or how "dangerous" the change is, so would leave
this to my R core colleague (BCC ed).
