An assignment appears to have an additional " " at the end of $2 (and $3) in preexec:

    % preexec() { echo "== preexec =="; set -x; test $1 = $2; echo $3; set +x }
    % foo
    === preexec ==
    +preexec:0> test 'foo=' '=' 'foo= '
    +preexec:0> echo 'foo= '
    foo= 
    +preexec:0> set +x

Please note that 1="foo=", but 2 and 3 are "foo= ".


Regards,
Daniel.
