Subject: [PATCH v2 0/2] bootconfig: Handle an empty value

This is the 2nd version of the update of the bootconfig parser to
make it handle an empty value which is terminated by a newline or
a comment. The previous version is here:


In this version I decided to make this change as an update instead
of a fix, since this can change the syntax rule which has been
accepted. In the previous change, it does not handle the array
correctly. This version fixes it[1/2].

Also, I added another patch to improve the test[2/2]. Previously
it just check the parse error, but it did not check whether the
good examples are formatted as it is expected. New test compares
the output so that we can ensure it is parsed as expected.

Thank you,
