commit b804e8851c33b68caa5057e809a12333741dfe2e
Author: Richard Kimberly Heck <[email protected]>
Date: Wed Jan 16 11:13:53 2019 -0500
Rename emergency file when it is kept.
Otherwise, we will ask about it again next time, when the file
may have changed. Also, if we crash again, we'll over-write that
file, which we may not want to do.
See bug #11464.
