Ok, so IINM, Anders' original commit was about making "git submodule
foreach <command>" behave more like "<command>" (from a naive user's
perspective), while you rather expect to insert quotes/escapes to
finely control exactly when shell interpretation happens. Aren't these
POVs mutually incompatible? Is the only 'real' solution to forbid
multitple arguments, and force everybody to quote the entire command?

I don't particularly care which way it goes, as long as (a) the common
case behaves as most users would expect, (b) the uncommon/complicated
case is still _possible_ (though not necessarily simple), and (c) we
don't break a sizable number of existing users.
