Okay. I didn’t know this. Has this change in recently? I remember
hitting on the group and opening the target file. But true, with
multiple results in the group that would be confusing.

There are two options here:

1. We just change the message. Something like: "select a match to open".

2. In addition to above, we may have a customization variable. Something
   like - xref-open-first-match

For this bug, (1) should be sufficient.
