+
+       * quotearg.h: Allow multiple inclusion by surrounding with
+       "#ifndef QUOTEARG_H_".  Include <stddef.h>, for size_t,
+       so that we can be included first.
+       (PARAMS): Remove; we now assume C89 or later.  All uses removed.
+       * quotearg.c: Include quotearg.h immediately after config.h.
+       No need to include stddef.h or sys/types.h any more.
+       Surround local include files with "", not "<>".
+       Assume HAVE_LIMITS_H unconditionally, as we assume C89.
+       Similarly, assume HAVE_C_BACKSLASH_A, CHAR_BIT, UCHAR_MAX, UINT_MAX,
+       HAVE_STDLIB_H, HAVE_STRING_H, STDC_HEADERS.
+       (HAVE_MBSINIT): Undef if !HAVE_MBRTOWC.
+       (mbsinit): Define to 1 if !defined mbsinit && !HAVE_MBSINIT.
+       (ISPRINT): Remove; no longer needed now that we assume C89.
+
+       (clone_quoting_options, quotearg_buffer, quotearg_n_options):
+       Preserve errno.
+
+       (quotearg_buffer_restyled, quotearg_n, quotearg_n_style,
+       quotearg_char): Use SIZE_MAX rather than
+       (size_t) -1 when we are talking about "infinity".
+
+       (quotearg_buffer_restyled): Fix bug when quoting trigraphs.
