When `len < 1`, len has to be 0 or negative, emit_line will then remove the first character and by then `len` would be negative. As this doesn't happen, it is safe to assume it is dead code.

This continues to simplify the code, which was started in b8d9c1a66b (2009-09-03, diff.c: the builtin_diff() deals with only two-file comparison).
