Recent keeps only files on disk, and its cap never drops an open one

A renamed scratch never saved and a /virtual/ pane were recorded as recent files, and at 200 the oldest entry went even when that file was open. Opens, renames and closes now record a path only when it is a file on this host, and the cap drops the oldest closed entry. A name with a newline is not written to the kept list, where it would read back as two.
