+ * xmemcoll.h, xmemcoll.c: New files.
+ * Makefile.am (libfetish_a_SOURCES): Add them.
+ * memcoll.c: Include errno.h, and declare errno if not defined.
+ (memcoll): Set errno to zero if there is no error.
+
+ * quotearg.c (quotearg_buffer_restyled):
+ Fix bug with quoting buffers containing NUL when backslashing escapes.
