This looks dubious to me. What if I already have a compilation buffer 
open, and I'm using `xref-find-definitions' to follow the implementation 
of some code near one of the errors?

This seems like it'll break the error chain I'm currently following.

Also, when I'm using xref-find-definitions (as opposed to the other 
xref-find- functions), I'm very unlikely to want to visit all results. 
It's usually just one that I'm after.
