Export snapshot and errors...

[Paul Dupuis]

According to the Dictionary, if I am reading it correctly, in a command 
(vs function)

return empty -- sets both 'it' and 'the result' to the parameter of the 
return statement (in this case empty)
return empty for value -- sets 'it' to the parameter (empty) and clears 
'the result' indicating no error (empty)
return empty for error -- set 'the result' to the parameter (empty) and 
clears 'it' (empty) indicating no value returned from the command

So, yes, "return empty" will do, but I choose to use "return empty for 
error" to remind me that it is purposefully 'the result' that I wanted 
to clear.
