It's compiled in. You need to re-compile with an increased setting of
DIMLBUF (and perhaps MLBUF) in console.c. (Almost all scrolling terminals
do have a fixed maximum history buffer, often much less than that one.)
I am not sure why you would want to to this though: you can avoid the limit
entirely by running Rterm.exe, or saving excessively long output to a file
with sink().
