  Update bug status by moving fixed bugs to bugs/resolved directory.  Added
  bug005.diderot -- error in handling redefinition of variables
  bug006.diderot -- don't catch programs without outputs
/****************
Compiling this program gives:
[sqr-bug02.diderot:22.32-38] Error: undeclared variable 'foobar'
uncaught exception Fail [Fail: Error in compiling sqr-bug02.diderot]
  raised at common/phase-timer.sml:76.50-76.52
  raised at common/phase-timer.sml:76.50-76.52
  raised at driver/main.sml:27.39-27.76

So there is both the "Error" and the "Fail".
When there is a descriptive Error message, why have
all the uncaught exception stuff?
