2.6.29 (first that had this script) allows for escaped double-quotes.
The oldest I tested, 2.6.20, also allowed escaped double-quotes.

The scenario involves an upper-layer build system that:
- is responsible for settings the kernel options based on global
configuration (eg. the same kernel build for different boards)
and/or options set by users (eg. I want USB camera support)
- uses scripts/config to set/unset options rather than implementing
its own logic
- in this case the version string can be set to include the user's
name, which may contain double-quotes (eg. John "Ripper" Smith)
For projects that decided to go with a stable version as the development
base (and won't update for the foreseeable future), then this is a (minor)
inconvenience (although the fix is easily back-ported).

stable (and I do understand his position and your concerns).
