Pipe

Syntax:  pipe <command>
The pipe command is a more powerful version of the old converse command.
Whatever argument you supply to pipe gets prepended to everything you type
until you type '**' on a line by itself, at which time the pipe ends. This
is meant for people with cut-and-paste, so that you can do 'pipe tell rust'
and enter a big block of text, without having to type 'tell rust' every
line, and cut-and-pasting every single line you want to pipe.
