-An approximate method to merge from upstream is:
-
-	# Fetch latest from upstream (we also include some compat stuff)
-	$ CVS_RSH=ssh; export CVS_RSH
-	$ CVSROOT="anoncvs@anoncvs.netbsd.org:/cvsroot"
-	$ cvs co -d libedit -P src/lib/libedit
-	$ mkdir libedit/np
-	$ for f in src/common/lib/libc/string/strlcat.c \
-	>          src/common/lib/libc/string/strlcpy.c \
-	>          src/include/vis.h \
-	>          src/lib/libc/gen/unvis.c \
-	>          src/lib/libc/gen/vis.c \

-	> do
-	>   cvs co -P ${f}
-        >   mv ${f} libedit/np
-	> done
-	$ rm -rf src
-	$ cd libedit
-
-	# Remove files we don't need/use
-	$ rm -rf CVS TEST Makefile shlib_version *.[0-9]
-	$ (cd readline; rm -rf CVS Makefile)
-
-	# Rename files to match our naming
-	$ mv makelist makelist.sh
-	$ mv terminal.h el_terminal.h
-
-	# Remove NetBSD-specific bits
-	$ for file in $(find . -type f)

-	>   cp ${file} ${file}.orig
-	>   sed -e 's/#include "terminal.h"/#include "el_terminal.h"/g' \

-	> done
-
-then merge remaining bits by hand.  All MySQL-specific changes should be
-marked with XXXMYSQL to make them easier to identify and merge.  To generate
-a 'clean' diff against upstream you can use the above commands but use
-
-	cvs co -D "2011/10/23 17:37:55" [..]
-
-to fetch the baseline of most recent merge.
-
-Please feed any fixes to Jonathan Perkin <jonathan.perkin@oracle.com> who will
-endeavour to merge them upstream and keep diffs minimal.

- * keymacro.c: This module contains the procedures for maintaining
- *	       the extended-key map.
- *
- *      An extended-key (key) is a sequence of keystrokes introduced
- *	with a sequence introducer and consisting of an arbitrary
- *	number of characters.  This module maintains a map (the
- *	el->el_keymacro.map)
- *	to convert these extended-key sequences into input strs
- *	(XK_STR), editor functions (XK_CMD), or unix commands (XK_EXE).
- *
- *      Warning:
- *	  If key is a substr of some other keys, then the longer
- *	  keys are lost!!  That is, if the keys "abcd" and "abcef"
- *	  are in el->el_keymacro.map, adding the key "abc" will cause
- *	  the first two definitions to be lost.
- *
- *      Restrictions:
- *      -------------
- *      1) It is not possible to have one key that is a
- *	   substr of another.
