[BUG] Not emitting Cpp2 space changes Cpp1 parsing due to max munch

[JohelEGP]

Title: Not emitting Cpp2 space changes Cpp1 parsing due to max munch.

Minimal reproducer (https://cpp2.godbolt.org/z/Kej4Kr1na):

v: <T> == 0;
main: () = v<i32> == v<i32>;

Commands:

cppfront main.cpp2
clang++17 -std=c++23 -stdlib=libc++ -lc++abi -pedantic-errors -Wall -Wextra -Wconversion -I . main.cpp

Expected result:

auto main() -> int { v<cpp2::i32> == v<cpp2::i32>;  }

Actual result and error:

auto main() -> int { v<cpp2::i32>==v<cpp2::i32>;  }

Cpp2 lowered to Cpp1:

//=== Cpp2 type declarations ====================================================


#include "cpp2util.h"



//=== Cpp2 type definitions and function declarations ===========================

template<typename T> auto const& v = 0;
auto main() -> int;


//=== Cpp2 function definitions =================================================


auto main() -> int { v<cpp2::i32>==v<cpp2::i32>;  }

Output:

main.cpp2:2:33: error: a space is required between a right angle bracket and an equals sign (use '> =')
    2 | auto main() -> int { v<cpp2::i32>==v<cpp2::i32>;  }
