The reason this is more of an issue with if statements is that MANY other languages support an actual else-if statement. They need this due to their syntax and compiler and parser (you usually see it paired with languages that require an endif statement). C does not need it, because you...
This isn't one of those, though it does share some basics: a markup syntax for templates that are processed to give resultant text output. The main difference with preprocess.py is that its syntax is hidden in comments (whatever the syntax for comments maybe in the target filetype) so ...
