remotefilelog: add newlines to ui.log() invocations

The comment at the top of ui.log() says that the message should be a
newline-terminated string. When using the blackbox logger, if the string does
not end in a newline, the appearance in the file gets quite messy.

This sometimes leaves a string with just the newline as the message, these are
logged by the blackbox logger just fine. I don't know what other loggers do when
logging structured data and a message that is just the newline.

Testing tagging with the EOL extension

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > eol =
  > 
  > [eol]
  > native = CRLF
  > EOF

setup repository

  $ hg init repo
  $ cd repo
  $ cat > .hgeol <<EOF
  > [patterns]
  > ** = native
  > EOF
  $ printf "first\r\nsecond\r\nthird\r\n" > a.txt
  $ hg commit --addremove -m 'checkin'
  adding .hgeol
  adding a.txt

Tag:

  $ hg tag 1.0

Rewrite .hgtags file as it would look on a new checkout:

  $ hg update -q null
  $ hg update -q

Touch .hgtags file again:

  $ hg tag 2.0

  $ cd ..
