Subject: Substitution command & fails on third (second?) try
Reply-to: ddouthitt@mennonite.minister.net
Message-ID: <39D9BC79.32551.23FF0C@localhost>

Package: elvis-tiny
Version: 1.4

Do the following on a file:

:s/tcp/TCP!/
j
&
j
&

The first substitution works, then the first & , then on the second & 
it replaces the substitution string with a '~' character.

For example, given:

my-tcp
his-tcp
her-tcp
their-tcp

The results would be:

my-TCP!
his-TCP!
her-~
their-~

This is consistent.

I have a few fixes for elvis-tiny, one for bug #55407 (vi segfaults) 
and one for bug #73059 (substitute & fails on third substitution).

I've included them in the text below.  They're two separate patches; 
so cut them out into two files.

I don't know if I qualify as "maintainer" but I'll see if I can keep 
fixing and learning as time goes on.
