Subject: fix false positive in link_types_changed
X-Git-Url: https://sipb.mit.edu/gitweb.cgi/ikiwiki.git/commitdiff_plain/1a09cddd39d4e15c442973dc256bf91b3c27997c

fix false positive in link_types_changed

loadindex does not bother populating oldtypedlinks if there is no link
type. However, the code in link_types_changed assumed that if oldtypedlinks
is not defined, and typedlinks is, they must differ.
