Subject: [PATCH] don't show notes for --pretty=raw

The --pretty=raw format of the log family is likely to be
used by scripts. Such scripts may parse the output into
records on blank lines, since doing so in the past has
always worked. However, with the recently added notes
output, such parsers will see an extra stanza for any
commits that have notes.

This patch turns off the notes output for the raw format to
avoid breaking such scripts.
