Use git-merge in git-pull (second try).

This again makes git-pull to use git-merge, so that different merge strategy can be specified from the command line. Without explicit strategy parameter, it defaults to git-merge-resolve if only one remote is pulled, and git-merge-octopus otherwise, to keep the default behaviour of the command the same as the original. Also this brings another usability measure: -n flag from the command line, if given, is passed to git-merge to prevent it from running the diffstat at the end of the merge.
