I just saved the grep buffer into a a file and killed the buffer. When
I opened the file again, everything was as before: you can jump to any
of the found places. What makes this possible is the first line of the
buffer that makes sure that when you open the file, it is in grep-mode
and the current directory is set to wherever the search was executed
in the first place:

I replaced real NUL chars above with the string "^@" because gnus
warned me of potential problems when sending mail with NULs: in the
real file, they should be real NUL chars.
