A propos of "bugger all," is anyone else familiar with "damn all,"
specifically in the following context:

  "And there's damn all."  I believe it means, "and that's that," or,
given Professor Horn's citation, short for "there's damn all i can do
about it."

  It still seems like an awkward shortening.  I came across it in
Schaffer's _Equus_.  Dysart is talking about his marital problems.
