allow to specify a remote in the publish command

[glehmann]

this is especially useful when working with github's hub (https://github.com/github/hub), to submit a pull request:

git clone git@github.com:kennethreitz/legit.git
git checkout -b my_branch
# code
git commit -am "my changes"
git fork
git publish glehmann
git pull-request

I realize this is a non backward compatible change. Any idea for a better implementation is welcome!

The current implementation is consistent with git push, i.e. both git push <REMOTENAME> <BRANCHNAME> but breaks backward compatibility.

On the other hand, git publish <BRANCHNAME> <REMOTENAME> will not introduce non backward compatible change, but may feels confusing since the order is reversed as git push.

Maybe git publish [branch] [--to remote_name]? And the corresponding option for unpublish is git unpublish [branch] [--from remote_name]?

git clone git@github.com:kennethreitz/legit.git
git checkout -b my_branch
# code
git commit -am "my changes"
git fork
git publish --to glehmann
git pull-request
# after merging pull request
git unpublish --from glehmann

Another choice is let legit to be a bit "smart", if it detects there are two remotes naming origin and USER (USER is github.user in ~/.gitconfig, if not set, falling back to login name), then legit assumes origin is readonly and both publish/unpublish use USER as remote. This also applies to sync, though the logic will be a bit complicated, i.e. fetch from origin but push to USER.

Just some random thoughts.

@glehmann Are you done with the changes? Can you please update the PR. Thanks

Another idea just occurred to me.

If legit detect there is a remote named foo, then publish foo will use foo as the remote. Otherwise foo will be considered as a branch name, and publish foo will publish the branch to origin.

Strictly speaking, this is still a non backward compatible change, but it probably will affect less issues to existing users since few people use the same name for both the branch and the remote.
