Editor backup files

[Conrad Hughes]

My editor (vim) creates backup files automatically, which in the case of
'pass edit' is something of a security leak — it'll fill your editor
backup dir with files like

  %dev%shm%pass.xyzxyzxyzxyzx%xyzxyz-passentry.txt~

One way around this is to configure the editor not to create backups
when editing in /dev/shm.  Have people taken any other approaches?
