Side note: when using git-ls-tree, the "blob"ness information is already in the tree output itself and you shouldn't even need to check the type with "-t". So what is perhaps somewhat more interesting is actually the mode of the file, since that determines whether the blob should be interpreted as regular file content or as a symlink.

Ie you can have a tree like this:

	100644 blob f2ba8f84ab5c1bce84a7b441cb1959cfc7093b7f    abc
	120000 blob f2ba8f84ab5c1bce84a7b441cb1959cfc7093b7f    file

where the first one is a regular file called "abc" (which contains the string "abc"), and the second is the _symlink_ that points to "abc".

They share the exact same blob, and what distinguishes them is the filemode info from git-read-tree.

Of course, the symlink case isn't very common and likely not very interesting in this case, but the fact that "git ls-files" is set up so that you can just cut-and-paste the "blob <sha1-of-blob" part and feed it to git-cat-file was definitely not just coincidence.

(A number of the early stuff was set up so that I could do things by hand by just doing cut-and-paste of the output of the previous command. Git has come a long way in the last 12 months ;)
