It turns out this doesn't work: if you specify individual files to
commit from the index, then git also includes any changes to those files
in the worktree too, and you can't ask it not to, because --only is
implied whenever files are supplied on the command line.
In other words, when vc-git-patch-string is non-nil, we mustn't pass a
list of files to git. So if there are files not involved in the commit
with staged changes, we need to stash those.
I tried implementing that, which is not hard, but then we pop that
stash, the staged changes aren't restored to the index. The result is
that if the user has a mixture of staged and unstaged changes to a file
which is not part of the commit, then afterwards the unstaged changes
will have been unstaged, mixed in with the staged changes again. In
some circumstances this could constitute a loss of work.
There are a few ways to overcome this. We can use the --staged option,
but that's only available in very recent versions of git. We could
perform a complex double-stash:
- git stash push -k -- foo
- git reset -- foo
- git stash push -k -- foo
- [commit]
- git stash pop
- git add -- foo
- git stash pop
Or we could do something like what Magit does to stash only the index.
Any thoughts on what would be best?
In the meantime, I've pushed a version of my previous patch, as I think
it makes sense to implement the stashing, if we do, as a second change.
