+ BASH PATCH REPORT
+ =================

+Bash-Release: 4.2
+Patch-ID: bash42-047
+
+Bug-Reported-by: Matthew Riley <mattdr@google.com>
+Bug-Reference-ID: <CA+NEdkwP3gw+gbcF5+xnR1pvcuzb1mDVzvmuJOpHRGHA9T7VFg@mail.gmail.com>

+when it should use memmove. The result is garbled pathnames in prompt
+strings.
+
+Patch (apply with `patch -p0'):
