It's recently come to my attention that the "git alias" config functionality

This ensures that the plumbing commands always work as expected.
As scripts *should* only use plumbing commands, the scripts should
work with high probability despite all the crazy user configuration/aliases.
Exactly.
For example, I wanted to setup "git clone" to automatically act as "git
clone --recursive". Sure I could do it in the shell, but it's more of a
pain - any tutorial I set up about doing it would have to worry about what
shell the user was using - and if you're going to make that argument, why
have "git alias" at all? It can all be done from the shell.
I think the git way for your example would be to configure git to include that
option by default, something like
git config --global submodules.recursiveClone yes
though I was skimming through the man page of git config and did not find
that option there. I guess it's missing.
We thought about adding such a config option, but I believe that would
fall a bit short. If I want to have recursive clone I also want to init
all those submodules appearing in later fetches too (otherwise the end
result would depend on whether you cloned before or after a submodule
was added upstream, which is confusing). Extra points for populating
the submodule in my work tree when switching to a commit containing
the new submodule.
So what about a "submodule.autoupdate" config option? If set to true,
all submodules not marked "update=none" would automatically be fetched
and inited by fetch (and thus clone too) and then checked out (with my
recursive update changes) in every work tree manipulating command
(again including clone).
Users who only want the submodules to be present in the work tree but
not automagically updated could set "submodule.autoupdate=clone" to
avoid the extra cost of updating the work tree every time they switch
between commits. Now that Heiko's config-from-commit changes are in
master, someone could easily add that to fetch and clone as the first
step. We could also teach clone to make "submodule.autoupdate=true"
imply --recursive and execute the "git submodule" command to update
the work tree as a first step until the recursive checkout patches
are ready.
Does that make sense?
