An idea that didn't work out (integer formatting)

[jepler]

I noticed there were two implementations of integer printing, one for printing object ints and the other for printing C ints. (mp_print_int vs mp_print_mp_int).

I thought: hey, on platforms with (mpz) long integers, we can create a long integer without allocating any memory, and get rid of the extra implementation of decimal conversion.

Oops, mpz_as_str_inpl does allocations down inside. So it recurses infinitely (or until it hits a stack limit) through m_malloc_fail.
