hello,
I think it is not obvious for everyone how to deal with Standard Input in the
`cat'-command. I took some time to figure out, that Ctrl-d aborts it. and just
now I realized, that EOF the first time acts to terminate a so called "record"
(I got the term from "info coreutils 'tac'"), and applied twice terminates the
Standard Input. If <newline> was typed before it is enough to type it once.
So I think it would be helpful for some people if in the documentations
man/info cat there would be at least a reference, if not a short explanation
how to deal with Standard Input.
