On OS X Mountain Lion (10.8, released 2012) and later, ddd 3.4.0 installs a
0-byte ddd.1 manpage because:


sed -f ./unumlaut.sed ddd.man | cat > ddd.1~ \
            && mv ddd.1~ ddd.1
sed: 4: ./unumlaut.sed: RE error: illegal byte sequence


Both unumlaut.sed and ddd.man are in ISO-8859-1 encoding. sed on OS X 10.8 and
later defaults to requiring its input to be UTF-8. If it is not, you need to
tell sed what encoding it's in by setting LC_CTYPE as in the attached patch.

It would also be great if errors from sed were not silently ignored as they
are now, due to the pipe. Piping to cat is a useless use of cat; removing it
would fix the problem, though I understand that on some other platforms it
does something other than cat here and so you may not want to remove it. But
maybe there is some other way to satisfy that other platform that does not
allow the build to proceed after an error has occurred.
