Without marks you cannot have the SHOWN mark at that point; we haven't
traversed the commits.

Why would a 'reset' command be expected if the 'first' branch is
already pointing to the 'first' commit?

Ditto, plus, why would 'git fast-export second' do anything regarding
'first'? It wasn't specified in the committish; it's not relevant.

Before an after my patch the output is the same:

% git fast-export first:
reset refs/heads/first
commit refs/heads/first

% git fast-export second:
reset refs/heads/second
commit refs/heads/second
commit refs/heads/second

Which is expected and correct; the branch already points to the right
commit, no need for an extra reset.
