Yep, now I can only totally agree with you.
I think you should open a JIRA.

I think this is enough to demonstrate that there's an issue.
Deleting without the 'where' clause returns (correctly) no rows
affected when there's nothing there. Using a '<=' operator in the
'where' clause seems to report the right values (2 when it deletes
2 rows, 0 when it deletes 0 rows). Going back to '=' reports 1 row
regardless.
This is 4.3 on CDH5, by the way.

Is not the output the number of lines of the delete command,
which is one line (the command itself) and not the number of
deleted lines?
Can you try to put some rows into the table and do the delete
again? Or try without the where close too?

Any idea why sqlline would report 1 row affected when I
delete no rows?
