A 100G file was ok in those editors even with syntax highlighting. That is an extreme because saving did take some time but there are ways to optimize for that would it ever become popular. IMHO 640K per file is enough for everybody.

  dd if=/dev/urandom bs=1M count=100k| tr -dc 'A-Za-z0-9\n' | fold -w 130 > largefile.c

For Emacs, there’s a package for editing very large files: <http://elpa.gnu.org/packages/vlf.html>
