;; Status file migration fails with removed and unavailable recipe

;; Just install some package to make sure el-get creates the
;; appropriate directories

;; Set up the status file with a removed package that has no current
;; recipe available.

;; Now try to read the status file. Without a fix, it will try to read
;; the recipe for "nonexistent-package" and fail, throwing an error.

;; Try to write package's status as "removed", which will also convert
;; the status file to the new format. Without a fix, it will again try
;; and fail to find the nonexistent recipe.
