Yes, this is exactly what happens.  We have thousands of source files
in our tree and most have names longer than 20 characters.  Our normal
usage pattern is to use partial matching.  Also your patch uses
tag-partial-file-name-match-p, not tag-full-file-name-match-p, so
it's not surprising that it should do partial matching with possibly
more than one match :)

With etags we were used to using "C-u M-." a couple times too, or
start over with a longer substring of the file name we wanted.

I'm not complaining about this new behavior; it will just take a
little getting used to.  Personally I like the fact that M-g M-n
works with the *xref* buffer like it does in a *compilation* buffer.
