It is also not specified to do so. 'getdelim' is a glibc invention, and
the glibc manual says:

   "If an error occurs or end of file is reached without any bytes
     read, `getline' returns `-1'.
    ...
    [getdelim] is like `getline' except ..."

without mentioning errno.

If you change the gnulib implementation without also changing the
glibc and the cygwin implementation, it buys you nothing.
