svn commit: r343884 - head/lib/libc/stdio

Log:
  GC a historical artifact.
  
  Back in 1993, the fgetln (then fgetline) interface was changed to not
  return a C string.  The change was accomplished by ifdefing out the code
  that did the termination.  Changing the interface would violate our API
  stability rules so remove the old implementation.
