OK, xdiff's xdl_recmatch() takes counted strings, and line[len] is
one byte beyond the end of the line (where LF typically sits), which
is the same convention as how "emitted_symbol" represents a line, so
not just the implementation replaced with a known-working one, but
also the code calls the helper with correct calling convention ;-)

Likewise. Looks good.
Will queue.
