[OpenSIPS-Users] Correct syntax with statement if

[Liviu Chircu]

Hi, Dmitry!

They are identical, regardless of the presence/absence of any code below.

It's not about correctness, rather readability.  Example 1 uses 3 LoC, 
while example 2 uses only LoC and it more readable, thanks to the 
absence of the braces.

I recommend going through the Linux kernel coding style 
<https://www.kernel.org/doc/html/v4.10/process/coding-style.html#placing-braces-and-spaces> 
docs, there is a "placing braces and spaces" section, which includes 
several if-statement examples, with braces, "else" blocks, etc.  Why not 
borrow the same ideas for our own /opensips.cfg/ coding style? :-)

Best,
