It is not.  That is a limit on line length.

It is a limitation of cut-and-paste.  That has limits depending on

- the OS
- how it is done (e.g. X11, GNOME, OS X) ... most OSes have multiple 
mechanisms, including Linux (which this was).
- where it is pasted from
- where it is pasted to.

We were told this was Linux: the most likely limitation is the terminal 
into which this was pasted.
