[PATCH] branch: segfault fixes and validation

branch_get() can return NULL (so far on detached HEAD only) but some code paths in builtin/branch.c cannot deal with that and cause segfaults. Fix it. While at there, make sure to bail out when the user gives 2 or more arguments, but only the first one is processed. Reported-by: Per Cederqvist S
