I think, Zefram is right - te problem has something to do with "am"
capability. Here is the example of input and what ZSH outputs (catched
with truss):
the input:
bor@itsrm1:~%> aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaa '
quote> bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
bbbbbbbbbbbbbbbbbbbbbbbbbbbb '
I do return and then recall previous command. ZSH outputs:
write(10, 0x082FA92C, 212) = 212
a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a
a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a
a a a a a a a a a a a a a a a a a a a a a a a a '1B [ 0 K1B [
0 m\r\n b b b b b b b b b b b b b b b b b b b b b b b b b b b b

b b b b b b b b b b b b b b b b b b b b\n b b b b b b b b b b b
b b b b b b b b b b '1B [ 0 K1B [ 0 m
Note, that the first line is output _without_ \n; but on the second line
ZSH outputs exactly 80 characters and then \n - if terminal really
implements "am", it gives you one more empty line.
The escapes output are (sorry, terminfo): "el" and "rmso"
It seems to be terminal-dependent, wether this effect happens. I tested on
4 terminal(emulations) - two vt-like,one ansi-like and xterm. Two have
this problem, two (including xterm) not.
hope it helps
