extra, empty tags in acedumps

[Dave Matthews]

I'm seeing some unwanted extra stuff in my acedumps, apparently related to
the timestamping.  For example, the empty tags Authority and Data_source in
this record:

// data dumped from tree display

Probe : "AC1"
Locus    "Xcnl1-7B"
General_remark   "Repeat sequences (TG)18"
General_remark   "Product size 157 in Geneva PI505819"
PCR
PCR_primers      "GCTGTAAACTCCATTGTTTGG"
PCR_primers      "CACAAATCGGCGAAAAC"
Amplification_conditions         "Annealing temperature 52 C, 2.50 mM MgCl2"
Wheat_polymorphism       "5 alleles \/ 18 germplasm lines"
Authority        "Blake, Tom"
Authority
Authority        "Sorrells, Mark E."
Data_source      "Blake, Tom" "95.08.24"
Data_source
Data_source      "Sorrells, Mark E." "95.09.13"

These are also present when the dump is made from tace.  No empty tags are
seen when the object is viewed with xace.  Tace shows this:
