So far a search path reference has been a syntax region, which is a very lax match for the strict rules from the actual Nix expression parser and if there is a single < operator, the syntax highlighting for the rest of the file is going to be messed up.

Of course, this also matches the operators we actually want to match, which are <, >, <= and >=.
