metaedit: allow operations on merge commits with some conditions

As with fold (see the previous patch), it's allowed to metaedit a merge commit
or a set of commits including merge commits (with --fold) as long as there are
less than 2 parents of the set not included in the said set.

#require test-repo

  $ checkflake8() {
  >   if ! (which flake8 > /dev/null); then
  >     echo skipped: missing tool: flake8;
  >     exit 80;
  >   fi;
  > };
  $ checkflake8

run flake8 if it exists; if it doesn't, then just skip
