I took a closer look and it seems the parsing code for addKerningClass
and alterKerningClass seem to have gotten swapped, so I think the
parsing for alterKerningClass needs to be fixed, too. But there is
other trouble when I try to 'save' or 'generate' a font to which I
have added a kerning class; I get segmentation faults in code for
dumping devicetables.

For 'save' I get this:

Program received signal SIGSEGV, Segmentation fault.

SFDDumpDeviceTable (sfd=0x1795c00, adjust=0x10) at sfd.c:657

For 'generate' this:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 47207199472928 (LWP 17309)]
0x00000000005e1c69 in dumpgposkernclass (gpos=0x17987c0, sf=0x1635b60, sub=0xb6cc10, at=0x7fff64079390) at tottfgpos.c:1399

Another issue, if I am correct, is that getKerningClass doesn't
include a 'None' class for the first class, but addKerningClass
expects it.

It's nice to have scripting for kerning classes. :)
