Subject: _really_rewrite_record() now checks whether the new ID has changed
X-Git-Tag: CPAN-v1.02~519
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=4821715139270e318a3387ed2f421596b0ad68dd;p=irspy-moved-to-github.git

_really_rewrite_record() now checks whether the new ID has changed
from the old, and if so prepares to delete the old record -- but does
not attempt to actually do so, since it seems that Zebra can't service
the request.
