Btw, I think I've found another "issue" with xref-find-def: it uses
the TAGS table information without any tolerance.  So if you have a
TAGS file that is slightly outdated, you are put on the wrong line.
By contrast, etags.el had special code that would look around the
position specified by TAGS, see etags-goto-tag-location.

And one more thing: after invoking M-. and typing the function name,
then typing '.' to get the first candidate displayed, if I switch to
the window where that candidate is displayed, the window switches
buffers on me, so that the function I wanted to look at disappears.
What am I doing wrong this time?
