[armedbear-devel] Patch: call reinitialize-instance on metaclass on class redefinition

I found out that ABCL, when redefining a class, modifies the old class
metaobject in-place, slot by slot. This has the implication that the
redefinition of an instance of a custom metaclass does not update
custom slots. Now, I didn't check on the AMOP, but I'm pretty sure the
proper class redefinition protocol is more articulate than the one
implemented in ABCL; still, applying the patch that you find attached
fixes the problem of custom slots not being updated by calling
reinitialize-instance where the old code manually updated the class
metaobject, so it is, I think, a valid temporary solution until we
have a full MOP. However, before committing the patch, I'd like to
hear your opinion about it.
The patch also includes some tabs converted to spaces, sorry for the noise.
