+       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.
