The maximum sizes aren't much increased though, as the limit of
process address space will be hit soon after. Which for a 32-bit Linux
typically is somewhere between 2 and 3 GiB. So yes, there are some
file sizes which can be edited in addition, but that range is rather
narrow.

I still think that --without-wide-int is the more reasonable default.
Users who need those big buffers or files can easily flip the option.
