Subject: [PATCH] org-persist.el: Customise persistence of data for remote
files
* lisp/org-persist.el (org-persist-remote-files): New defcustom
defining strategy for persisting data associated with remote files.
Separate strategy is necessary to avoid unexpected password promtps
while garbage collecting the cache: remote files may require server
login.
(org-persist-gc): Decide whether to store remote file data according
to `org-persist-remote-files'.
