Sure, but the decompiler can choose to always decompile to "else if {", which is more readable and more likely to match the original source code.

That's my point. The compiler's choice of "else if {" or "else { if" is unrelated to the programmer's choice.

It does and at least the current dotPeek 2017.2.2 decompiles it to else if and does, other than I thought, not allow to customize it.

Obviously whatever decompiler was used here decided to do it the other way.
