TAGS buffer be readonly..

Hello

Since ESC . just reads from tags-buffer (TAGS), it seems that makes
sense that it open the "TAGS" buffer in a read-only mode.

(the default  gets bad for me because:
 
One of my emacsen is busy setting tags for me for the latest
functions/software..

In the other (main) emacs, i will have called ESC . in past, which starts to
"edit" the tags buffer!  then my emacs will be running some elisp
program, when the program will be suddenly disrupted by:
"TAGS modified. Really edit? " 

whereas i never asked the emacs to edit the TAGS in the first place.
I wished it just 'visited' the TAGS table...
)


Thanks
