Package: coreutils
Version: 8.23-4
Severity: grave
Justification: causes non-serious data loss
Dear Maintainer,
The command 'cat > somefile' truncates input lines longer than 4096
characters.
To reproduce:
[[[
% yes | head -2049 | xargs | xclip -i # copy 4098 bytes on a single line
% xclip -o | cat > foobar && wc -c foobar # no problem when stdin is a pipe
4098 foobar
% cat > foobar && wc -c foobar
<paste><EOF>
4096 foobar
]]]
In the above, <paste> represents using the X11 "paste" action (such as
middle-click or shift+insert) and <EOF> represents pressing <Ctrl+D>.
I expected the full 4098 bytes to be pasted.

Nope, cat doesn't do it. There's a 4k kernel line length limit on
terminal input.
You can put the terminal into raw mode with "stty -icanon" but then you
won't be able to ctrl-d (that's part of the input processing).
Nobody has changed the 4k limit because in general it's a curiosity
rather than a workflow impediment.
