In plan9port, this script will re-load any clean window that differs from
an existing file with the same name:

```
#!/usr/local/plan9/bin/rc

cleanIDs = `{9p read acme/index | awk '$4 == 0 && $5 == 0 { print $1 }'}
for (id in $cleanIDs) {
nm = `{9p read acme/$id/tag | sed 's/ .*//'}
if (test -f $nm && ! cmp -s $nm <{9p read acme/$id/body}) {
echo get | 9p write acme/$id/ctl
}
}
```

If you make it deal gracefully with acme not running, you could probably
have git call it automatically whenever you check out a different revision.
Caveats: this does nothing for directory windows, doesn't help with files
that exist in one branch and not another, won't touch a dirty window, and
has been tested very little.

By the way, Russ's Watch is here:
