+	* job.c (construct_command_argv_internal): Sanitize handling of
+	backslash/newline pairs according to POSIX: that is, keep the
+	backslash-newline in the command script, but remove a following
+	TAB character, if present.  In the fast path, make sure that the
+	behavior matches what the shell would do both inside and outside
+	of quotes.  In the slow path, quote the backslash and put a
+	literal newline in the string.
+	Fixes Savannah bug #1332.
+	* doc/make.texi (Execution): Document the new behavior and give
+	some examples.
+	* NEWS: Make a note of the new behavior.
