And here it is for reference with the matching change in test-oidmap,
and the adjustments necessary for the test scripts (from master, not
from my earlier patch). I think I prefer the simpler "just sort it all"

The post-image in t0016 may be a new low: a command substitution in a DQ
string fed to echo, itself inside a command substitution in a here-doc.
Yuck. :)
