I am very fond of this patch. Still, the fact remains that until this command is implemented by some other fast-import backend, it is hard to know what git-specific concepts are encoded in its current implementation. (I am in particular worried about what should be gauranteed about the blob_identifier in the blob blob_identifier 1823 line and whether cat-blob blob_name cat-blob :11 are going to overlap and cause trouble for some backends.) On the other hand, development of svn-fe continues to benefit from cat-blob and its cousins ls-tree and ls. and there has been brief discussion of using cat-blob to make cvs2git more friendly. So here's a reroll, since it seems clear that this feature should be in future versions of fast-import in some form. Thoughts welcome, as always (even as simple as "I have a bad feeling about this" or "everything in this patch looks ready to go"). Patches based against v126.96.36.199 for no particular reason.
