org-crypt: when running `org-decrypt-entry', only run `auto-save-mode' check if on an encrypted entry
* lisp/org-crypt.el (org-crypt-check-auto-save): New function, see next change.
* lisp/org-crypt.el (org-decrypt-entry): Break the auto-save-mode check out
into a separate function, and call it at a later point, to assure it only
runs when visiting an encrypted entry.
Currently `org-decrypt-entry' is doing the auto-save-mode check whenever
it's run, regardless of context, while this only makes sense when run on
an entry which is actually encrypted (or looks like it, at least).
