Also I updated the jc/pull-signed-tag topic that follows Linus's
suggestion to always spawn an editor when running "git merge" in an
interactive session.  The special-case environment variable has been
renamed to MERGE_AUTOEDIT, and scripts can set it to "no" when they start
to accept the autogenerated merge log message.  There is no plan to
encourage humans to keep using the historical behaviour, hence there is no
support for configuration variable (e.g. merge.autoedit) that can be set
to 'no'.
