etags to xref changed navigation

[Phillip Susi <phill@thesusis.net>]

Etags used to work by hitting ( I think it was ) M-. to find the first
reference, then M-, to cycle through the remaining references.  It seems
that when it was replaced with xref, the M-, binding was removed, and
now M-. opens an xref buffer ( splitting the window ) listing all of the
references, and you have to navigate that buffer in one window while
viewing each location in another.

I find this process slow and cumbersome compared to the old way of just
jumping from reference to reference.  Is there a way to get back to the
old behavior?
