not in POSIX, thus it should have a config option and be disabled by default:

so please create a test case in the hush test subdir

i'm pretty sure your implementation handles this incorrectly.  this:
unset A; export -n A=1
should result in A being set to "1".  yours does not do this from what i can 
see.  by fixing that, you should be able to combine the ugly memory management 
your change addes with the existing xstrdup() in the code.

you've also got whitespace damage and useless comments (pretty much every one 
i saw was unnecessary).
