This is a problem with the C++ ABI.  In C, as mentioned, adding an
empty string doesn't change anything.  Since the C++ interface is
broken by design and requires a character you'll have to handle a NUL
character special and, yes, probably set the grouping string to a
value so that the code does not try to group anything.

And I agree with it, it is correct.  And not only for glibc, it's
generally correct.  ISO C uses an empty string to denote no thousands
separator.
