REVISION SUMMARY
  In 8a0e03f7baf4 <https://phab.mercurial-scm.org/rHG8a0e03f7baf4e2639519ef787324b591bd5d9d82> (remotefilelog: move most setup from onetimesetup() to
  uisetup(), 2019-05-01), I said:
  
    All the wrappers moved in this patch check if remotefilelog is enabled
    before they change behavior, so it's safe to always wrap.
  
  That was clearly a lie, because getrenamedfn() didn't. That made
  e.g. `hg log -T {file_copies}` unbearably slow. This patch fixes that.
