In both termui and on the command line, I can search for certain labels, but I can't search for bugs that don't have the label. eg:

    git bug  ls -l foo  # lists all bugs with label "foo"

It would be nice if there was an inverse label search. For example:

    git bug  ls -L foo  # lists all bugs that don't have label "foo"

this would be useful for many things.
