/*! Reimplementation of `yes(1)`, that does not die from SIGPIPE`.

A common idiom in UNIX computing is to prepend `yes |` to a pipeline in order to
get interactive scripts to act without user input. The coreutils implementation
of `yes(1)` crashes from SIGPIPE when the pipeline ends.

This program does not.
