Looking at
https://dev.minetest.net/Lua_code_style_guidelines
I read the following about Lua source code:
> Conditional expressions have continuation lines indented by two
> tabs.[*]
For Emacs, replacing 'tabs' with 'indentation level', this would be
```
if long_function_call(with, many, arguments) and
another_function_call() then
do_something()
end
```
However, this is not what Emacs does by default in Lua mode; you
rather get
```
if long_function_call(with, many, arguments) and
another_function_call() then
do_something()
end
```
which makes the code hard to read.
Assuming that this functionality is available, how can I activate this
in Lua mode? Otherwise I wonder whether I should file a bug report.

[*] Another recommended way to format multi-line conditionals is
described at
https://roblox.github.io/lua-style-guide/#newlines-in-long-expressions
```
if
long_function_call(with, many, arguments)
and another_function_call()
then
do_something()
end
```
However, this becomes ugly if you are going to use `else` and
`elseif`.

Is this about lua-mode from Non-GNU ELPA? Or about some other
package? Because Emacs doesn't include such a mode, AFAICT.

Oops! Indeed, this is not part of Emacs. Sorry for the noise, I will
report the problem elsewhere.
