I don't want to pay for --with-wide-int in my builds because I almost
never look at such large files.  But I'd be happy to be able to look at
such large files every once in a while.

Whether it'd be significantly slower depends a lot on whether we keep
most buffer positions as C integers or as Lisp integers and how often we
convert from one to the other.  I don't have a clear enough idea about
that to venture a guess.
