Subject: (store_symval_forwarding): Delete special read-only
X-Git-Tag: ttn-vms-21-2-B4~10754
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=999e64847e279e0b10464311207cc1cb4622dd43;p=emacs.git

(store_symval_forwarding): Delete special read-only
hack for type == -1, since we now use ->constant instead.
(Fkill_local_variable): Don't use XBUFFER if it can be nil.
