Subject: sed: handle the unspecified "n as delimiter alias" case more sensibly

Print the less-surprising variant in a corner case of POSIX-unspecified
behavior.  Before, this would print "n".  Now, it prints "X":
  printf n | sed 'sn\nnXn'; echo
* sed/compile.c (match_slash): Remove special handling of 'n'.
