It looks like we now have separate tables for EHL and JSL; we probably
need to handle them with separate tables now.

These last two entries might have already changed again in the bspec
since you wrote this. For EHL I see:
0x6, 0x7f, 0x38, 0x00, 0x07
0x6, 0x7f, 0x3f, 0x00, 0x00
(i.e., the third column is slightly different). And the JSL table has
other deltas as well since it just got added.
