Comment (by Tarrasch):

 Did you see my comment in the commit message? I reproduce it here:

 ''There's no way to reuse the code for say [P, P] and [P, N], since the
 juxtaposing of code and data when compiling with TABLES_NEXT_TO_CODE.''

 Well I guess it still applies if you don't compile with
 `TABLES_NEXT_TO_CODE`.

 Here is some more elaboration: If you intend to share the code but have
 two different tables, you do that by letting the "code-entry-pointer" in
 the two tables point to the same code. But there's no such "code-entry-
 pointer" field with `TABLES_NEXT_TO_CODE`.
