[tex-live] tlmgr backups listed multiple times

[Maxwell, Adam R]

I've noticed a slight oddity in tlmgr's backup listing (Mac OS X, using tlmgr from today's tlcritical).  Available versions of some packages are listed multiple times.  For example, ltxmisc has

20188 (2010-11-08 17:57) 20088 (2010-10-25 14:01) 19964 (2010-10-25 08:12) 19851 (2010-10-25 08:12)

and repeats that 4 times.  In fact, there seems to be a pattern; if N backups are available, the list of 1-N is printed N times:

$ tlmgr restore ltxmisc
Available backups for ltxmisc: 20188 (2010-11-08 17:57) 20088 (2010-10-25 14:01) 19964 (2010-10-25 08:12) 19851 (2010-10-25 08:12) 20188 (2010-11-08 17:57) 20088 (2010-10-25 14:01) 19964 (2010-10-25 08:12) 19851 (2010-10-25 08:12) 20188 (2010-11-08 17:57) 20088 (2010-10-25 14:01) 19964 (2010-10-25 08:12) 19851 (2010-10-25 08:12) 20188 (2010-11-08 17:57) 20088 (2010-10-25 14:01) 19964 (2010-10-25 08:12) 19851 (2010-10-25 08:12)
