Subject: skiphead, a program to preserve headers in a pipeline

This is a faster, more robust rewrite of a shell script I wrote a few
years ago to preserve headers when grepping through program output. I
can never remember what the headers are when I run things like 'ps', so
being able to say something like 'ps -ef | skiphead grep systemd' is
useful.

As a bonus, the program detects your locale and automatically displays
help and error messages using the correct encoding.
