---------------------------------+------------------------------------------
 After test 0023 glob file copy in the ext2test.fth the filesystem is left
 in an inconsistent state as reported by e2fsck on build 881:

 {{{
 bash-4.1# e2fsck -f /dev/sda1
 e2fsck 1.41.12 (17-May-2010)
 Pass 1: Checking inodes, blocks, and sizes
 Pass 2: Checking directory structure
 Entry 'f.tst' in / (2) has deleted/unused inode 26.  Clear<y>?
 }}}

 It is the last file deleted in the script that is affected.

 Tested on a 128MB and a 2GB USB flash drive.

 The minimum reproducer is an olpc.fth file containing:
 {{{
 \ OLPC

 to-file u:\f.tst cr
 del u:\f.tst
 }}}

 Adding a ''dir u:\'' command to the end of the reproducer prevents the
 symptom.  Theory: a cache is flushed.

 Entering the commands interactively instead of using \boot\olpc.fth makes
 no difference to the symptom.

 Deleting a pre-existing file does not produce the symptom.
