Also, how does this work if I run

expr -i 0 -u 0 -- not a valid expression

The command string here is `-i 0 -u 0 -- not a valid expression` but you probably don't ever echo that full line onto the diagnostic, so either you are fudging and only matching the args part of the command, or the docs aren't right here.
