Comment (by RolandSenn):

 After looking into the code, I decided the following:
 The requested functionality is not a ''dump'' operation. In a dump
 operation we have information in memory and write (dump) it out to sysout,
 syserror or to a file. Here, however, we have the information already in a
 file and we want to keep the file after GHC processing ends. Hence, this
 is a ''keep'' operation, and the flag will be called '''keep-hspp-file'''.
