I did a time profile on ee while it loaded a large file.
The profile indicated that printing the current number of lines
to the screen consumes about 30% of the
load time (counting all the statements involved in that process).
It's hard to measure exactly, because you have to
exit ee as soon as possible after loading the file,
which only takes a few seconds on my Pentium.

Converting the tabs and removing the \n only accounted
for 4%. ed also converts tabs (for .e and .ex files only).

int_to_bits() consumed a lot too, but I think
that's in the loop where ee waits for a key to be pressed,
so it doesn't matter.
