Scrollback editing leaving possibly world-readable files in /tmp

Further information
I noticed when editing the scrollback, via search -> e, a file ending in .dump is created in /tmp and opened in the editor. However, when quitting the editor, the file stays around. Shouldn't it be deleted once the editor exits? I'm on a shared host. The file is not readable by others, which is good (though hopefully not dependent on umask).

Unfortunately this seems to honor umask, making the scrollback fully readable in /tmp:

valankar@pontus ~> ls -l /tmp |grep valank                                                                                                                                                                                                                                        (base)

I suggest if not auto-deleting, to force the permissions to be unreadable by others. Otherwise there is a lot of information other users can get from these files.
