Early in the Bash-completion script, we build up a string that identifies the command or subcommand. When we see the top-level command's name (e.g. `git`) we set the command so far to that value. We do that regardless of where in the argument list it appears. For example, if the argument list is `git diff git`, we set the current command to `git` when run into it the second time. We therefore suggest arguments to the top-level command afterwards, which is not correct. This patch fixes that by also considering the string that identifies the command so far, so we only set the overall command to `git` if the command so far is the empty string. This is actually just a step on the way to getting completion to work for aliases of subcommands. Closes #4273
