One idea would be to detect this situation at M-. time -- that is, when
TAGS tells us about a file that doesn't exist, ignore the bad result and
re-run etags --prune or whatever.

The reason I added --find was to circumvent both this problem (though as
you saw, I didn't actually write this part) and also to deal with a
couple other problems: the need to avoid Makefiles (gcc and gdb have to
be built out-of-tree, which is a pain for running "make tags"), and
consequently the need to have the config be accessible to etags itself.
