It doesn't matter.  Whatever is more convenient for reading and
understanding the rules is preferable.

Separate patches, please.

Please also include with the patches the relevant additions to the
etc/HELLO file, and also don't forget to make sure
script-representative-chars has representative characters for the
script -- this is important for selecting fonts for those characters.

However, if you intend to submit more patches, I suggest to start your
legal paperwork of assigning the copyright to the FSF, so that we
could accept those future contributions from you.  If you agree, I
will send you the form now.
