The Autoconf manual suggests against unsetting IFS instead of resetting
it to the default sequence for yet another reason: if IFS is unset, code
that tries to save and restore its value will incorrectly reset it to an
empty value, thus disabling field splitting:

    unset IFS
    # default separators used for field splitting
    # ...
    # code using the new IFS
    # no field splitting performed from now on!

Not sure how this is relevant for the Git codebase, but maybe it is
something worth reporting in the commit message of a proposed patch.
