One issue I still see is that if TAGS is slightly outdated, point is
positioned not on the first line of a function/macro/struct, but on
the line recorded in TAGS.  I hope this will be fixed soon.

Another minor issue is with the help-echo in the xref buffer: it says
"mouse-2: display, mouse-1: navigate", which is confusing because it's
unclear what exactly each of these 2 means.  How about saying
explicitly "show in this window" and "show in another window"
(assuming this is what that does)?

Finally, I still think we need to allow searching symbols not only in
the current buffer's programming language, at least with the tags
back-end.  Without that, we cannot deprecate find-tag.
