Doesn't look like a bug to me.

agreed.

No, he's done exactly what he wanted, which is to explicitly define a
new station name and equate it to an existing one (without distorting the network).

There is no reason why therion should issue an 'accidentally created
station' warning about this.

It's not non-existant - that's the point. It exists, but has no explicit position.

I disagree. This is a rather odd use of 'no-survey', but it seems to me to be valid.

I wouldn't go to all this trouble just to make the names shorter, but
if one wants to do that I see nothing wrong with it. 

It would perhaps be better to invent an 'alias' command for simple
alternative name of existing points, which is what Vasily actually
wants (except that Survex has already defined an alias command which
does something slightly different, so maybe it would have to be
altname or something).

Vasily - you might want to file this as a 'wishlist' item on the therion github.
