Steve,

Ok, here goes:
If a command is typed, the first Enter is still ignored, the second is
accepted, the command is executed, and then the shell exits (see
steve_o-paste-sh.strace, the command typed was 'ls').
If no command is typed, Enter exits the shell (see
steve_o-paste-sh1.strace).
Some more info: a lone Enter now kills cat as well.  Strace attached
(see steve_o-paste-cat.strace, the characters typed were
'a<Space><Enter>b<Enter><Enter>').
	Igor
