dirstate: enforce context set_clean and set_possibly_dirty

We don't want them called within a `changing_parents` context, but we still want
them called within a context.

So we update the decorator accordingly

fixbundle() {
    grep -v 'saving bundle' | grep -v 'saved backup' | \
        grep -v added | grep -v adding | \
        grep -v "unable to find 'e' for patching" | \
        grep -v "e: No such file or directory" | \
    cat
}
