Considering git-commit doesn't allow this (probably for good reason),
is it technically safe to do the following sequence of events?

tree=$(git-write-tree)  #basically the same tree HEAD points to
commit=$(echo $IDEAS | git-commit-tree $tree -p HEAD)
git-update-ref HEAD $commit HEAD

I figured all a commit is doing is taking a snapshot of a particular
tree at a moment in time.  And taking multiple snapshots at that same
moment and stringing them together (pointed to by HEAD) wouldn't be a
big deal.

Am I going to wind up shooting myself in the foot later or will this
work?  Light testing didn't show any issues.  Thought I would ask the
experts.  Thanks.

No, it won't break anything.

Great.

I do that empty commit myself for a different reason.  I wouldn't
recommend that you do that with public history, and since the file
didn't change in that commit you cannot do `git log -- foo.c` to
see which notes you wrote about foo.c.  But `git log` will still
show you the messages.

Hmm.  Good point.

Cheers,
Don
