Nothing a simple Lisp function couldn't handle, if installed as a hook
in a proper place, right?

And the period is no longer an issue, so you are down to caps.

Relax, this ain't NASA, and I'm not your boss ;-)  I do expect my
advice to carry some weight, but not enough to prevent you from
arguing if you feel strong about not using caps (or whatever is the
issue at hand).

The "squashing" part is optional.  Personally, I prefer not to (if
nothing else, it makes bisecting more accurate, and also lets me
recall what I've done and why more easily), although the benefits are
minor, and some people do prefer squashing.

Then don't squash.  It's not required.  The single merge-commit is
good enough to make this a single changeset, from the mainline POV.

Asterisks come from add-change-log-entry and friends, so it will not
be there if you just write free text, like I did above.

In any case, the asterisks are optional, IMO.  They don't carry any
information with them.  I've been deleting them until now, but I hear
some people want to keep them.  Other projects are inconsistent wrt
this, although most of those I looked at do leave the asterisks alone,
probably because it's easier.

all that's really required.  Beyond that, it's all about your
perfectionism.

Should be fine.

I'd suggest "optionally squashing the commits".

Thanks.
