It would be nice if Lua script crashes could produce a stack trace on the demon screen.

Might have to move from Lua 5.1 to Lua 5.2 for this.

There are some stackoverflow questions that seem relevant. I spent about a half hour trying to make something work, and couldn't.

Ok, this should be fixed now. BTW, I don't know what I meant by "Might have to move from Lua 5.1 to Lua 5.2 for this.", since digging through the logs, we've been using Lua 5.2 the entire time, the first commit using Lua is from 2013: 429a409dfd3e5b57c3900a39b24eec2cae3f1cd0 and it uses 5.2.

So, the following commits have been made:

• dece3e54cc5dd45f82ffdcb589e7e89b3e16961c Remove last two params of do_lua_pcall
• eb801dbb20e565646eb6c0e6f498b0bf1330bda8 Handle newlines in demon console
• a69de7af8b81f143e5413faf7225061f7ad5848d Allow do_lua_pcall() to print Lua stack traces
• 7cf6e70e1d56cabc084fe773ffd423a2d1046c6f snis_server: Factor out demon console message helper function
• f338cf514023c2c315dd462f41f1e2662a6b99b5 Break server console message boundaries at newlines

Now we get nice Lua stacktraces like this:
