grep cannot find relative file names after save and re-open

[Dan Nicolaescu]

Try this: 

emacs -q 
C-x C-f $YOUR_EMACE_SOURCE_TREE/lisp/ChangeLog RET
M-x grep RET defface */*.el RET
C-x C-w /tmp/TEST RET
C-x k TEST RET 

now open /tmp/TEST

C-x C-f /tmp/TEST RET
now move the cursor to one of the "calendar/calendar.el" lines and
press RET

at that point you are prompted to enter the file name where the file
"calendar.el" is found.
