FR: Style immutable nodes differently in log

[martinvonz]

Is your feature request related to a problem? Please describe.

jj log doesn't indicate which commits are immutable.

Describe the solution you'd like

We should indicate in some way which commits are immutable. Maybe we would use a ◆ symbol for it.

Describe alternatives you've considered

Mercurial (at least with the setup we use at Google) does it by coloring the commit id differently. We could do that in addition or instead.

A slightly related thing that could be done here as well is configurable node symbols.

So there will be a generic config, something similar to node.default = '◉', node.immutable = '◆', maybe also node.working-copy = '@' although we had a bunch of discussions about how wc being @ is important because the revset symbol for wc is @

Slightly less related thing is having said config for any number of arbitrary revsets, not just immutable, I think that was also mentioned by someone.

I don't know if there were any feature requests for any of above

@martinvonz Perhaps, current issue could be closed, since there is #3260?
