That gave me the idea of moving the `include.path` setting higher up in
the file, to see if `git checkout` would consult that value first, but
it doesn't work; `git config merge.conflictStyle` shows the value from
the file indicated in `include.path`, but a command like `git checkout`
still dies based on the value in ~/.gitconfig.

Overall this points to the general problem that it is not only hard to
make a single config that works on different machines, but it's hard to
make a _combination_ of files that works on different machines.

For now, I think my workaround is going to be templating out
machine-specific files.
