It is interesting that we came to a slightly different conclusion,
after doing pretty much the same analysis ;-).  Unless Ben has a
plan to use a version that trims the trailing LF elsewhere, there is
no point changing what the function does, especially because the
existing and only caller does want the terminating LF at the end.
