If so, we would have added ..., but we couldn't, because <src> was
not such a local ref.
But is that a useful/actionable piece of information? The user said
v2.19.0^{commit} because there was no such local ref the user could
have used instead to allow the DWIM to work on the destination side.
Perhaps it may be a good thing to remember for the next time, but it
does not help the user at all while redoing this failed push.

I am not sure if this is an improvement, quite honestly.
The only part that directly matters to the end user and is is more
understandable than the original is "You must fully qualify the ref"
(by the way, that dash is probably not what you want). As I already
said, "if this were local ref we can guess the location, it would
have worked better" is not relevant to the end user, so it is a
better use of the extra bytes to explain what it is to "fully"
qualify the ref, than telling what would have helped us make a
better guess. Perhaps something along the lines of...
'newbranch' does not match any existing ref on the remote
side. Please fully specify the destination refname starting
from "refs/" (e.g. "v2.19.0^{commit}:refs/heads/newbranch"
for creating a "newbranch" branch).
