'{{ }}' in code is treated as Liquid tags by jekyll

[xlucn]

e.g. in a1020, there is one line of code:

node nodes[CNODE] = {{post, in, N}}, *p = nodes, *n;

The warning message says

Liquid Warning: Liquid syntax error (line 76): Expected end_of_string but found comma in "{{post, in, N}}" in /home/luxu/Code/PAT/_articles/a1020.md
