Subject: [PATCH] Fix inclusions of readline/editline header files so that we
 only attempt to #include the version of history.h that is in the same
 directory as the readline.h we are using.  This avoids problems in some
 scenarios where both readline and editline are installed.  Report and patch
 by Zdenek Kotala.
