if all=& in |yawn, it will delete all listeners ducts,
without notifying them about it, which seems bad,
so we migh adress that separatedly.
Also, it might be cleaner to have a separate task instead of
a flag, to have two paths for "remove me" and "remove all",
this way there won't be an option for a listener to remove all
others, and that will have to be handled explicitly.
This commit refactors `sur/hood.hoon` and changes the signature of the
`+vats` generator thus:
```hoon
|= $: [now=@da eny=@uvJ bec=beak]
$@(~ [?(%suspended %running %blocking %nonexistent) ~])
$: verb=?
show-suspended=?
show-running=?
show-blocking=?
show-nonexistent=?
==
==
```
Called with a single positional argument, `+vats` will show only those
desks fitting the description given, while keyword parameters allow
finer-grained control over which desks are described. The `verb`
parameter determines whether the full load of desk information be shown,
or a subset thereof.
Resolves#6297.
if you're trying to tombstone at the head of the desk, you probably
don't know what you're doing. so we abort.
we keep the option to `|rm` any matching hashes in other desks since
this is something the tombstoner might not know exists in advance and is
actively blocking them from completing the desired tombstone operation.
This should no longer go into dill, but instead be controlled by drum
directly, since that's where system output gets rendered now (in the
common/default case).
wasn't properly descending into directories next to files with the same
name.
now offers to remove files that can't be tombstoned. can choose to
remove the file at the head of the current desk or from the files on
other desks sharing the same hash.
