By default, the log invocation now shows at least 5 ancestors of the
current working copy branch. This makes it much easier to get situated
to the current location for me - otherwise, if I just pushed my main
branch and thus there is the main bookmark just below my commit none of
the last couple changes are shown in the log. If there are fewer than 5
ancestors it will just show however many there were.
Instead of aliasing the revset I am always using currently, we simply
set it to be the default for any log command. If we want a different
revset we can still supply it. Other aliases keep different revsets
(e.g. `jL` variants for `all()` revsets).
Git commits, on push, will be signed by default (just like my git
configuration itself) but *not* every change is signed since that is a
hassle with the working copy technically also being an ever changing
git commit.
Additionally, added a private-commit option which will refuse to push
commits beginning with 'wip: ' to any remote, which is not super useful
for my current use cases but also a nice feature and fun to experiment
with for the future.
