PlugUpdate does not handle new branches

[sloria]

Ran into a bug when trying to pass the branch option with a newly-created branch. It seems that PlugUpdate does not fetch new branches because I get the following error:

error: pathspec 'issue23' did not match any file(s) known to git.

I had to manually run git fetch in the plugin's repo folder before executing PlugUpdate for it to work.

Thanks for the report. This is what vim-plug does on update:

git checkout -q NEW-BRANCH 2>&1 &&
git pull --progress --no-rebase origin NEW-BRANCH 2>&1 &&
git submodule update --init --recursive 2>&1

I'm not completely sure yet but I guess adding -B option to the first command will solve the issue.

git checkout -q -B NEW-BRANCH 2>&1 &&
git pull --progress --no-rebase origin NEW-BRANCH 2>&1 &&
git submodule update --init --recursive 2>&1

EDIT: Using -B is obviously not the right solution.
