Make pull -u behave like pull && update

Previously, pull would not update if new branch heads were received,
whereas pull && update would move to the tipmost branch head.

Also change the "crosses branches" abort in merge.update from
"crosses branches (merge branches or use --check to force update)"
to
"crosses branches (merge branches or update --check to force update)"

since it can no longer assume the user is running hg update.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR"/printenv.py <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
