patch 8.2.1970: it is easy to make mistakes when cleaning up swap files
Problem: It is easy to make mistakes when cleaning up swap files after the
system crashed.
Solution: Warn for the process still running after recovery. Do not
automatically delete a swap file created on another system.
(David Fries, closes #7273)
