+	Avoid double-quotes inside backquote inside double-quote.
+	* gettext-runtime/m4/po.m4 (AM_PO_SUBDIRS, AM_POSTPROCESS_PO_MAKEFILE):
+	Remove unneeded outermost double-quotes around backquote that contains
+	double-quoted strings. Avoids an idiom that nearly triggers a ksh bug.
+
 2010-06-04  Bruno Haible  <bruno@clisp.org>
 
 	Prefer documented low-level autoconf macro names.
