When function = comint-redirect-results-list-from-process is examining the
output buffer of the command it attempts to skip past the = command if it

However, this test uses looking-at and = so will fail if the command

(defun example ()

    (process-send-string p = "quit\n") = ;; cleanup!
    (message (car = reply)) = ;; this should be the a time of the file
    reply

File = example.el creates a shell process then runs =E2=80=9Cirb=E2=80=9D, the = ruby
interactive shell, then sends it a command = with question-marks in it.
The first line returned = should be the atime of the file.
