Add pools ignore in exclude option

[cmp168]

[pdf]

What if pool and dataset names overlap? I suspect this probably needs to be a separate flag, but could be convinced otherwise.

[cmp168]

Separate via regexp in docs used ^rpool

[pdf]

What if I want to exclude the dataset rpool, but not the pool rpool?

[cmp168]

--exclude='^(.+)/rpool/(.+)$' or /rpool, first '/' imposible in pool name

[pdf]

The top-level dataset name and the pool name cannot be differentiated - there are no slashes, and dataset names are never preceeded by a slash:

$ zfs list -o name rpool
NAME
rpool

$ zpool list -o name rpool
NAME
rpool

[cmp168]

aha, not bug is feature)). But for always valid result need more what 12 string changes, default dataset name in pool with not default name unlikely, maybe replace if c.excludes.MatchString(p) { to if c.excludes.MatchString("pool:" + p) { and use --exclude=pool:rpool, but i not sure is good idea

I guess you could do it this way, but simpler and more discoverable to just add a separate flag.
