Looks good, but what is slightly confusing is that it doesn't map
one-to-one to the RESTRICT tokens:
- RESTRICT="mirror" enables mirror restriction, and it is undone by
"mirror+", as expected.
- RESTRICT="fetch" enables both fetch and mirror restriction, but it is
undone by "mirror+" as well, not by "fetch+" (which disables only
fetch restriction).
I had already asked this in bug 371413 [1], but is there an actual usage
case for example 3? Because if there isn't, we might get away with only
supporting "mirror+", which should be less error prone.
