It has to do with "AS" saving the text in a macro.  This results
in part of the eqn code being already evaluated while saving the
abstract, not when it's being processed for printing.  The only
way I see to prevent this is to edit the macros (m.tmac):

In the definition of "AS", immediately before the line
".de cov*abstract AE", add the line

  .eo

and in the definition of "AE" (which is currently empty, it
seems), add the line

  .ec

With these changes eqn code works normally in the abstract.
