I highly doubt that you would want to be "backward compatible" in this
case, though.
The section of the configuration you are enclosing the new if/endif
syntax may be
understood only by newer Git (e.g. imagine core.pager is still
bool-only today), and
older Git that do not understand if/endif syntax will happily read
that section and
choke on it, no?
