[libdnet-devel] blob_insert bug

[Brian C. <bm...@sh...>]

There is a bug in blob_insert, as it has src & dst swapped in the 
memmove command.

The proof is in the pudding:

	blob_t *b;
	char tmp[32];

	b = blob_new();
	blob_insert(b, "foo", 3);
	blob_rewind(b);
	blob_insert(b, "bar", 3);
	blob_rewind(b);
	blob_read(b, tmp, 6);
	tmp[6] = 0;
	printf("GOT %s\n", tmp);

You should get "GOT barfoo", but it does not.  Currently, it gives 
"bar".

Attached is a patch that corrects this bug and and updates the test 
cases for insert & delete to actually test values instead of return 
codes.
