Add alt code for 1993/lmfjyh

Why? Because! :-)

Updated .gitignore.

Added the entry to bugs.md.

refers to make alt.

The README.md file was updated including succinctly giving the gist
(that might or might not be redundant :-) ) of the entry i.e. how it
worked (though the author also stated this).

 If not enough args are specified this program will likely crash or do something
 else. This should NOT be fixed.
