Sounds good. The teased-apart topics can also be found at

The latter. A quick search (web search + codesearch.debian.net)
reveals that most callers to submodule foreach either pass a script as
a single quoted argument (e.g.,
http://stackoverflow.com/questions/8364738/bash-git-submodule-foreach:
git submodule foreach '[ "$path" = "Libraries/JSONKit" ] \
&& branch=experimental \
|| branch=master; git co $branch'
or http://sources.debian.net/src/jquery/1.7.2+dfsg-3/Makefile?hl=131#L131:
git submodule foreach "git pull \$(git config remote.origin.url)"
) or pass a one-off command with no arguments intended for the shell
(e.g., http://sources.debian.net/src/libreoffice/1:4.1.1-1/g?hl=352#L352,
http://sources.debian.net/src/swi-prolog/6.4.1-3/scripts/newversion?hl=81#L81):
git submodule foreach git push "$@"
git submodule foreach git tag -s -f -F $tmp $gittag
So I suspect this will fix more scripts than it breaks, though it may
still break some. :/
It might make sense to warn when passed multiple arguments and some
include shell metacharacters, since that's probably rare, too, except
it's punishing people who use multiple arguments as a way to avoid
quoting issues. Probably there's no replacement for just advertising
the change loudly and seeking out scripts it could break.
Thanks,
Jonathan
