You don't tag individual files.  Git is snapshot based.  You tag
the entire project at once.

The comment you quoted was talking about tagging a single listing of
blobs (a tree) or a single blob (stream of bytes).  This can be handy
in rare cases.  In the linux kernel for example the prior history
was stored by tagging the tree of that prior history, as there was
no git based history preceeding that snapshot, so there were no
commits to tag.  In git.git Junio publishes his GnuPG public key
as a tagged blob, making it available to validate signed tag objects.

So you can't tag individual files.  The comment is a bit misleading
and gets far too low-level for an otherwise high-level conversion
guide.
