Reencode files from latin1 to UTF-8.

Avoid triggering autovivification of %config entries, which would result in
an empty addenda section.

Handle kernel configs that lack a "machine" line by guessing at the location
of GENERIC (assuming that it is in the same directory as the config file)

Don't forget to check defined() before testing the value.

Recognize options with values. If an option is present in both GENERIC
and the custom kernel, but its value has been modified, it will now be
kept in its correct spot instead of being moved to the bottom.

Comment lines may have leading whitespace.

Add -c option to preserve comments from GENERIC in the output.

Add genericize, a Perl script that converts a kernel config into something
more easily diffable against GENERIC.
