Here is my ~/bin/first script.  It uses a feature in MH 6.5
pick; if -list is specified, and nothing matches, the pick
command prints "0" so that other MH commands won't use their
default message sequence.  It also does all sorts of things
to be MH-like.

My script is basically the same as yours, except that it
passes options to pick instead of passing options to show.
This allows you to specify other folders besides the current
folder, and all sorts of other things like that.
