Recent and /recent keep PDFs and images as they keep files, and an open file's row is where its dot is now

Only text files were recorded, so a PDF read yesterday was not there to
find again, and an open file's row showed the place it last closed at,
stale by however far it had moved since. A PDF is kept at its page and
reopened there from its row; an image by its path; an open one's row
reads its pane's place at the time of the listing.
