Bug#480371: export -p should sanitize exported environement

[Vincent Bernat]

Hi!

Here is another  example of variable that should not  be shown in export
-p:

$ env 'bogus-variable=18' dash -c 'export -p' | grep bogus-variable
export bogus-variable='18'
$ dash -c "export bogus-variable='18'"
export: 1: bogus-variable: bad variable name

Thanks.
