Subject: git-branch-list(is_a_branch): Remove `$?` from `return`

I had forgotten when I wrote this, but the Bash help says:

> If N is omitted, the return status is that of the last command.

Meaning we don't need to explicitly return the code from the last
command as that's what happens by default.
