+	[BZ #12378]
+	* posix/fnmatch_loop.c (FCT): When matching '[' keep track of beginning
+	and fall back to matching as normal character if the string ends before
+	the matching ']' is found.  This is what POSIX requires.
+	* posix/testfnm.c: Adjust test result.
+	* posix/globtest.sh: Adjust test result.  Add new test.
+	* posix/tst-fnmatch.input: Likewise.
+	* posix/tst-fnmatch2.c: Add new test.
