It seems to have spread to Almquist shells like dash, but it's
definitely not in POSIX. That covers _most_ platforms these days, but
I'd guess would break on older ksh. We should probably avoid it.
For the curious, there's a very thorough discussion in the first answer
here:
http://stackoverflow.com/questions/18597697/posix-compliant-way-to-scope-variables-to-a-function-in-a-shell-script
In this case, we know that we're doing the sanitizing in a subshell, so
I think just dropping "local" and clobbering the existing
$sanitized_config is fine.
