Add 1992/adrian/try.sh

This script shows the entry itself as well as some of the other tools
that the entry generates. The adwc / wc one uses a pipeline to show the
output (with leading spaces and filename removed along with squeezing
spaces) and also writes each to a text file to use diff on, to show how
they have the same output.

Not all the tools are in the script. The adbasename might have a bug
(in any case it doesn't appear to function exactly like basename(1) in
that it requires two args, not one) so it is not used and adgrep is not
used either. For the latter one the author's remarks might provide some
clues as to why I did not include it.
