Junio C Hamano d04aa7ec47 Merge branch 'jc/merge-refuse-new-root'
"git merge" used to allow merging two branches that have no common
base by default, which led to a brand new history of an existing
project created and then get pulled by an unsuspecting maintainer,
which allowed an unnecessary parallel history merged into the
existing project.  The command has been taught not to allow this by
default, with an escape hatch "--allow-unrelated-histories" option
to be used in a rare event that merges histories of two projects
that started their lives independently.

* jc/merge-refuse-new-root:
  merge: refuse to create too cool a merge by default

# CVS LOG
#------------
# Known issues with git-cvsserver current log output:
# - Hard coded "lines: +2 -3" placeholder, instead of real numbers.
# - CVS normally does not internally add a blank first line
# or a last line with nothing but a space to log messages.
# - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
# tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
# it converts to local time zone. git-cvsserver doesn't do the +0000
# or the MT tags...
# - The latest 1.12.x releases add a "commitid:" field on to the end of the
# "date:" line (after "lines:"). Maybe we could stick git's commit id
# in it? Or does CVS expect a certain number of bits (too few for
# a full sha1)?
#
# Given the above, expect the following test to break if git-cvsserver's
# log output is improved. The test is just to ensure it doesn't
# accidentally get worse.
