[PATCH] fast-import: support the ls command anywhere comments are accepted

[Mike Hommey <mh@glandium.org>]

The git-fast-import manual page says about both cat-blob and ls that they can
be used "anywhere in the stream that comments are accepted", but in practice
it turns out it was only true for cat-blob. This change makes fast-import
behavior match its documentation.

The downside of this change is that if a script relies on the fixed behavior,
it won't work with older versions of git. I'm not sure it is better than
fixing the documentation to match the unfortunate current limitation?
