I just tried this.  With "cat *.h *.c > all.c" in the Emacs src directory,
the resulting file is 11 MB, for about 370K source lines.  Opening and
using that file, with c-mode, font-lock-mode, transient-mark-mode,
hl-line-mode and display-line-numbers-mode (and a few others), works
without any visible problems.  I tried e.g. to insert some code at random
places, to kill the second half ot the buffer and to yank it as its first
part, to query-replace-regexp the 1652 occurrences of "E\([^ ]*\)s " with
"Es\1 ", to narrow-to-region/widen, ...  The Emacs process did not use
more than 120 MB.
