So, I would say that rev^! is shorthand for rev^@..rev, but it does not actually work:

git rev-list 7ac749c^@..7ac749c fatal: ambiguous argument '7ac749c^@..7ac749c': unknown revision or path not in the working tree.

yet "^rev^@ rev" syntax does:

git rev-list ^7ac749c^@ 7ac749c 7ac749c96d143ba4f76723959892cbaddbe8ed07

Is it a bug or feature?

Puzzled...
