 I'd like to add the following /command name to the admin/execline
package:

 /command/pipe

 It's nearly impossible to perform some Google search to check whether
"pipe" is already used as a command; however, pipe(1) does not exist
on any Unixish operating system that I know. In case another name is
needed, I'd like it to be as close as possible to "pipe", because that
is exactly what the command does:
 pipe fdr fdw prog... creates a pipe from fdw to fdr, then executes
prog.

 Thanks,
