Yeah, I think that is probably more sane. We don't collect the
information now, but it probably wouldn't be that hard (at the very
worst, it would probably just involve running "uname" at build time).

You would need to provide git with some condition about which address
should be used. It sounds like the repo directory is the best bet. So
maybe something like:

  [include-ifrepo "/home/jsoffian/Work/*"]

or something. Maybe that's too gross. I dunno.

FWIW, this hack would work even with current git:

  cat >bin/git <<\EOF
  #!/bin/sh
  case "`git rev-parse --show-toplevel`" in
  "$HOME/Work/*")
          set -- -c user.email=whatever "$@"
          ;;
  esac
  exec /path/to/real/git "$@"
  EOF

which would actually work with most of the conditionals that have been
mentioned in this thread. But it's kind of nasty.
