bug#7021: 24.0.50; start-process + non-existing programs => status = run

[Andreas Politz]

Starting a process with `start-process' with a non-existing program
results in a file-error and a process having the status `run'.  I don't
know if it is supposed to be that way.

gnus uses something like the following in order to find a suitable
connection method.

(with-temp-buffer
  (ignore-errors
    (start-process "foo" (current-buffer) "nonexisting-program"))
  (process-status (current-buffer)))

=> run

With the same result of quering the user about killing the process
buffer, due to `process-kill-buffer-query-function'.
