I thought that was what it meant, too, but I couldn't reproduce the "bug"
that it was claiming to fix.

imadev:~$ bash-4.2.37 -posix -c 'readonly a=3; a=2 echo foo; echo survived'
bash-4.2.37: a: readonly variable
foo
survived

imadev:~$ bash-4.1.9 -posix -c 'readonly a=3; a=2 echo foo; echo survived'
bash-4.1.9: a: readonly variable
foo
survived

imadev:~$ bash-4.1.9 -posix -c 'readonly a=3; a=2 /bin/echo foo; echo survived'
bash-4.1.9: a: readonly variable
foo
survived
