Never understood that if statement style, it seems to only exist to create subtle bugs.
It's slightly less lines of code which is nice. I'm someone who prefers terseness so I get it.
However, it's bad. I much prefer the rare, elusive, postfix if:
goto fail if (condition);
It can create some very readable code when used right, with short and simple conditionals.
I think of it as BSD style, though of course it could be suggested/mandated elsewhere -
As I look, GNU guide is less specific, but examples[1] show the same style.The good thing is that -Wmisleading-indentation [2] (comes along with -Wall) catches this indentation error.
