To use the feature of core.attributesfile, the user needs:
- to create such a file,
- and add configuration variable to point at it.
Instead, we can define a filename that is unlikely to already exist on
the system, and only use the presence of the file as a cue that the user
wants to use that feature.
We could pick any random filename that only user can create, which
means that it has to be under $HOME. Let's use
"${XDG_CONFIG_HOME:-$HOME/.config/git}/attributes". It is as good as any
random filename in $HOME/ and follows the XDG specification.
