Re: [PATCH] interpret_branch_name(): handle auto-namelen for @{-1}

However, before we do that auto-namelen magic, we call
interpret_nth_prior_checkout(), which gets fed the bogus
"0". This was broken by 8cd4249c4 (interpret_branch_name:
always respect "namelen" parameter, 2014-01-15).  Though to
be fair to that commit, it was broken in the _opposite_
direction before, where we would always treat "name" as a
string even if a length was passed.

That commit is mine, by the way. More embarrassing than introducing the
bug is that I _noticed_ the problem at the time and wrote a paragraph in
the commit message rationalizing why it was OK, rather than just doing
this trivial fix.
