The user can specify this combination in a .gitattributes file and we
have to react to it *some way*. Theoretically we could document that
this combination is undefined and/or emit an error if we see this
combination, but we don't do so.

I'm still trying to infer the spirit of the current behavior, so caveats
here.
This comes from a real-life scenario where a user, somewhere early in
.gitattributes, had
* text
* eol=crlf
and then later (this could be in a subdirectory) tried to carve out
exceptions to this rule by using
*.png binary
* text=auto
Intuitively it *feels* like either of the later lines should suppress
EOL translation in PNG files (assuming the PNG file has a NUL byte in
the first 8k, which this one did).
It seems to me that setting "text=auto" should mean that Git uses its
heuristic to guess whether a particular file is text or not, and then
treats the file as if it had "text" or "-text" set. If the latter, then
EOL translation should be suppressed.
It also seems to me that "binary" should imply "-eol".
