"declare" when used in a function acts like "local", and creates a variable
with scope local to that function.  So does "declare -r".  But "readonly",
which is otherwise the same as "declare -r", creates variables with global

Is this intended?

Tested with 2.05b, 3.something, and 4.2.20.

I've also noticed weird behavior with "declare -gr" the r sometimes seems to override the g, but not specific to functions It seems to be specific either to the source file or to the compound statement. I haven't been able to figure out exactly whats going on there. I haven't been able to reproduce it in a simple example. this is most readily noticeable with set -o nounset
