I've got two branches, one which I commit to quite frequently and another only
periodically, call them inward and outward. Inward is where I do my work,
outward tracks an SVN repository. I'd like to merge inward to outward without
committing the merge so that I may provide a commit message appropriate for
checking in to the SVN repo.
`git merge --no-commit inward' from branch outward, I thought, should do it.
Performing a `git status' and a `git log' directly afterward seem to indicate
that the merge was committed. `git commit' insists the branch is now up to
date.
Am I going about this the wrong way? What does --no-commit mean, if I am?
(Also, I asked this on #git earlier. If anyone happens to idle there, pardon
me for re-posting this so quickly. I've got terrible lag this morning, enough
to time out frequently.)

Either it was a fast-forward (IOW, the outward had no changes since you
changed inward, and inward is derived from outward), or we have a bug
(which I cannot reproduce).

exactly what it say: do not commit. Fast-forwards do not commit, just update
your HEAD, index and working directory with the new changed (from inward
in your case).

If you want the "whole" set of changes from inward to appear in outward as a
/single/ commit with an appropriate commit message, probably you want to use
also the --squash option of git merge.
Otherwise, git will preserve the "structuring" of the history in many commits.
This means that:
- if outward does not need any real merge (because it only needs to be advanced
to a newer status and not to join some changes of its own with changes from
inward), git merge will make a "fast-forward". In other words, you will see
outward becoming up to date without the need of any merge-commit at all. BTW
that is why --no-commit appears to have no effect in this case: there wouldn't
be any merge commit in any case.
- if outward needs a real merge, then git merge will set up everything up to the
point of making the merge commit. Then, depending on the presence of the
--no-commit option it will or will not make the actual commit.
