Oh, sorry, I noticed this problem is just the tip of the iceberg,
so creating a separate bug report from bug#5042 and bug#9917.
The patch above fixes the problem of using xref-find-definitions
in elisp-mode, but using xref-find-definitions in narrowed
C files still fails with the error "Rerun etags: `%s' not found in %s".
Here is an additional patch that fixes this as well:
