Makes the code more readable and has a smaller number of memory accesses thus it's small optimisation as well. For _get_token() optimize number parsing. Check for '.' char only if it's not a digit. Move pointer incrementation into one place. For _eat_space() check only p->te for '\0' in skipping of comment line. Avoid check for '\0' when we know it is space. Also master while loop doesn't need checking p->tb for '\0'. We just need to check p->tb isn't already at the end of buffer. This could give 'extra' loop cycle if we are already there - but safes memory access in every other case.
