[REBOL] Re: newlines

I reckon you should check for any
whitespace characters after your first
two lines.
Actually, that's not the problem.
Try this instead of that useless knee-jerk
reaction.
s: "^/^/^/^/hello there^/^/^/^/^/"
while [p: find s "^/^/^/"][remove p]
It removes character by character,
if it keeps finding three in a row,
instead of replacing three with two
and placing the index after the two.
-- Explanation --
Pretend N is a newline in the original
string, and n is a new newline inserted
by our function.
Here's the string at the beginning,
with the index at the first position:
s: "NNNN"
^
Now, after we do [replace s "NNN" "nn"]:
s == "nnN"
^
The index is after the inserted replace string!
That means a subsequent REPLACE will only see
ONE newline character (the final "N").
But we really need to go back to the beginning
and see if the two ok-sized bits have joined
forces into a over-sized monster.
Anyway, the while loop above seems to solve it.
