mq: fix comment to reflect change in efbee27415ab

some implementations of cp can't create hardlinks

  $ cat > cp.py <<EOF
  > from mercurial import util
  > import sys
  > util.copyfiles(sys.argv[1], sys.argv[2], hardlink=True)
  > EOF

Test hardlinking outside hg:

  $ mkdir x
  $ echo foo > x/a

  $ python cp.py x y
  $ echo bar >> y/a

No diff if hardlink:

  $ diff x/a y/a

Test mq hardlinking:

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "mq=" >> $HGRCPATH

  $ hg init a
  $ cd a

  $ hg qimport -n foo - << EOF
