      7 # Until 2020-10-04, assigning the result of a shell assignment to .CURDIR
      8 # tried to add the shell command ("echo /") to the .PATH instead of the
      9 # output of the shell command ("/").  Since "echo /" does not exist, the
     10 # .PATH was left unmodified.  See VarAssign_Eval.
     11 #
     12 # Since 2020-10-04, the output of the shell command is added to .PATH.

     18 # A normal assignment works fine, as does a substitution assignment.
     19 # Appending to .CURDIR does not make sense, therefore it doesn't matter that
     20 # this code path is buggy as well.
