It watches the current dir and runs a given command if any file in this dir changes. Actually think of Watch more as inspiration!
You may be better off relying on git — watch .git/HEAD (changes when you switch branches) and watch what it is pointing to (changes when there is a commit or pull etc.), figure out what changed, which acme windows are relevant and update their body. There is still the issue of what to do if a file that changed has been edited. Or the file has been deleted or renamed. And there is a potential race — you may be editing a window when window body gets switched underneath! It may be better to print commands to do all this and leave it upto the user.
May be add a reload command that reads a window's tag and reload its body from the opened file.
Do you have a pointer to Russ's Watch? I quick dig shows I have poor Google-fu.
