Hi Tim,

sorry for the late reply, and thanks a lot for the clear summary.

After careful consideration, I suggest to follow the manual here,
which says that ":results value" is the default.

After 2f534294 in master, executing shell blocks with no :results
header will output the exit code, which is the "value".

I decided not to go that way, even though I do sympathize with Tom's
argument in the very same thread.  I think Jack makes a compelling
argument about the need to let the default always be ":results value".

It seems less random to have some users being surprised that the value
of executing a shell source block is an exit code, than to make it
necessary for all users to check what is the default result for each
Babel library.

Best,
