Quoting the manual:

‘value’
     Default.  Functional mode.  Org gets the value by wrapping the code
     in a function definition in the language of the source block.  That
     is why when using ‘:results value’, code should execute like a
     function and return a value.  For languages like Python, an
     explicit ‘return’ statement is mandatory when using ‘:results
     value’.  Result is the value returned by the last statement in the
     code block.

"0" is the _exit code_ of the successful echo command, not the value
returned by the echo command.

So In Vladimir's example, both ":results value" and ":results output"
should return the same result, i.e. ".".

Was it common to expect the exit code when executing shell code?
