Instead of copying the format string from flash to RAM before formatting, use vsnprintf_P to read the format string directly from flash memory. This eliminates: - The byte-by-byte copy loop from PROGMEM - The complex dual-purpose buffer management - Potential buffer overflow if format string is very long The new format_body_to_buffer_P_() function is a simple variant that uses vsnprintf_P instead of vsnprintf.
