shared.c: Only setenv() if value is non-null
Some setenv() implementations (e.g. the one in OpenBSD's stdlib) segfault if we pass a NULL value. Only set environment variables if the corresponding settings are defined to avoid this. Note that this is a minor behaviour change as environment variables were supposed to be set to an empty string if a setting was undefined. Given that this feature isn't part of any official release yet, there's no need to worry about backwards compatibility, really. Change the documentation accordingly.
