Emacs writes a temporary file as soon as you start editing a file. When you hit save, it removes the temporary file.

This triggers gow, since the extension is still .go. It's a bit ugly, though perhaps not the end of the world.

To avoid flag chaos, I think reading patterns from a file is probably nicest, but I could imagine using .gitignore-style patterns fits more with gows current style.

Would you be open to an ignore prefix flag, an ignore pattern [1] flag, or perhaps reading a .gowignore file?

And thanks for writing gow! It replaces an inotifywatch | while read; go make ; done loop I've used previously. Much neater.
