+       Getline touchups.
+       * lib/getdelim.c (getdelim): Revert regression that required *n to
+       be 0 when *lineptr is NULL.  Preserve errno across funlockfile.
+       * m4/getdelim.m4 (gl_FUNC_GETDELIM): Check for declaration of
+       getdelim, rather than whether implementation is missing.
+       * m4/getline.m4 (gl_FUNC_GETLINE): Likewise for getline.
+       * lib/stdio_.h (getline): Also declare if replacement is
+       required.
+       * doc/functions/getdelim.texi: New file.
+       * doc/functions/getline.texi: Likewise.
+       * doc/gnulib.texi (Function Substitutes): Add new files.
+       Reported by Bruno Haible.
