Hi,
the patch below fixes a bug in ext2fs_unlink() I came across when testing
my changes to e2fsprogs for 64KB blocksize support... Please apply.

Subject: Fix a bug in deletion of first directory entry in a second (or further) directory block
We cannot merge a removed directory entry to just arbitrary previous directory
entry. The previous entry must be in the same block. We check whether the current
entry is not the first one in the block and only if it isn't merge it to the
previous entry.
